Molecular Geometry and the Vapor Pressures of Isotopic Ethylenes: Chemical and Structural Isomers (open access)

Molecular Geometry and the Vapor Pressures of Isotopic Ethylenes: Chemical and Structural Isomers

The theory of isotope effects on vapor pressures for systems with large quantum effects, as manifested by the cross-over phenomenon and deviation from the rule of the mean, is illustrated by the large body of experimental data on the isotopic ethylenes which has recently become available. An effect of molecular geometry was found, viz. a difference in vapor pressures of cis-, trans- . and gemdideuteroethylenes. This was shown to be related to the hindered rotation about the C=C axis in the liquid. A further consequence of the hindered rotation was established, namely a perturbation of the out of plane molecular vibrations. This is a new effect for which a one to one correspondence with the molecular symmetry was established. Quantitative calculations show that this rotation-vibration coupling further enhances the effect of the hindered rotation. A theoretical calculation of the vapor pressure differences of the isotopic ethylenes from molecular data is made through statistical mechanical theory and the calculation of the energy states of the isotopic ethylenes. The agreement with the experimental data, which encompasses a significant number of different parameters, is quantitative.

The Ultraviolet Sensitivity of Frozen Phage (open access)

The Ultraviolet Sensitivity of Frozen Phage

Recent reports (1, 2, 3, 4, 5) suggest that the crystalline structure of ice permits unusual forms of energy relationships and that the structured state of water may be of importance in the whole cell. A number of biologically interesting compounds show significantly altered responses to the excitation energy of ultraviolet light in ice as compared to the liquid state. This paper describes the effect of a change in phase state on a biologically active nucleoprotein, a bacteriophage particle. Phage is found to be much more sensitive to inactivation by ultraviolet light when irradiated in frozen aqueous suspension than when irradiated at room temperature (7): the sensitive target appears to be the phage DNA.

Radiation Damage in Graphite. II. Consecutive and Steady State Reactions of Interstitial Complexes (open access)

Radiation Damage in Graphite. II. Consecutive and Steady State Reactions of Interstitial Complexes

Periodically irradiated and annealed graphites show property changes that are markedly different from the changes after the first irradiation and anneal. Evidence is presented indicating the existence of consecutive reactions between interstitial complexes that lead to steady state concentrations of the intermediate species in a chain. The steady state concentrations result in dimensional recoveries and stored energy releases that do not increase with irradiation as they do in continuously irradiated graphites. Interstitial complexes, formed by a thermal anneal, interact through an integral chain via mobile single interstitials. Kinetic equations of chains reacting at one or both ends are described. The calculations for chains reacting at both ends show that large complexes can decompose to form smaller ones. Experimental evidence supporting the calculations shows that periodic removal of the smaller complexes of large amounts of damage associated with the layer interstitials.

Mechanisms of Liquid Metal Corrosion (open access)

Mechanisms of Liquid Metal Corrosion

The driving force for liquid metal corrosion is the equilization of chemical potential for dissolution of all solid surfaces in contact with the liquid. In any practical system, this is an impossible goal; therefore, one observes several mass transfer processes.

Effect of Long-Range Interactions on Order (open access)

Effect of Long-Range Interactions on Order

Harrison and Paskin (HP) have calculated the ordering energy of β-CuZn using recent theoretical techniques of treating electron screening and Mott's polar model of an alloy. Good agreement is obtained between the calculated total energy of the order-disorder transformation and specific heat measurements. A consequence of the HP calculation is that the ordering energy is long-range and oscillates in sign. Walker and Keating recently measured the neutron diffuse scattering of β-CuZn above the critical temperature Tc and find their data is in agreement with order calculated by only considering a nearest neighbor interaction. Using the Cowley statistical theory of order, we compare the order generated by a nearest-neighbor interaction and the long-range interaction of HP at a temperature 1.1Tc. we find the average behavior of the order generated by the nearest-neighbor and long range interaction to be similar, The major difference is the nearest-neighbor interaction generates order that asymptotically, varies smoothly with neighbor distance whereas the order resulting from the long-range interaction fluctuates markedly about the nearest-neighbor generated order. This result may explain the success of statistical theories, based on nearest-neighbor interactions, in both order-disorder of alloys as well as in some magnetic systems which are also believed to have …

Past Analogue Multipliers with Field-Effect Transistors (open access)

Past Analogue Multipliers with Field-Effect Transistors

The solution time of analogue multipliers using field-effect transistors is investigated. This time is ultimately limited by the charging time of the field-effect transistor junction. In typical devices suitable for analogue multiplication the charging time is found to be about 10-20 nsec less than one percent. A four quadrant pulse amplitude multiplier circuit is described, whose solution time is equal to the field-effect transistor charging time.

Light-Droven Cytochrome Reactions in Anacystis and Euglena (open access)

Light-Droven Cytochrome Reactions in Anacystis and Euglena

The basic similarity in cytochrome physiology between Anacystis nidulans ad Euglena gracilis, strains Z, is impressive in view of their gross dissimilarities in size, structure, and pigment content. We have investigated the cytochrome reactions by sensitive spectrophotometric methods in order to gain some insight into the patterns of energy transfer from the various light receptors to the reaction centers involved in the two photochemical reactions of green plant photosynthesis and also to elucidate the pathways of photosynthetic electron transfer. The major thrust of this presentation will be the implications of experiments on whole cells in which both wavelength and intensity of monochromatic actinic light have been systematically varied. Some preliminary observations of the effect of carbonyl cyanide-m chlorophenylhydrazone (CCCP) are presented, and the light-driven reduction of cytochrome b6 in Euglena chloroplast fragments is described.

A Model for Current Reversal Chronopotentiometry with Kinetic Complications (open access)

A Model for Current Reversal Chronopotentiometry with Kinetic Complications

A model has been developed for the analysis of current reversal chronopotentiograms in systems where the electrode process is followed by a homogeneous second order reaction. The model is analyzed using the IBM 7094 digital computer programed in FORTRAN language. Working curved, derived with the aid of dimensional analysis, can be used to evaluate rate constants from experimental data. The electroreducation of uranium (VI) to uranium (V) with subsequent second order disproportionation of uranium (V) has been studied as an experimental test of the model. Disproportionation rate constants thus obtained are in satisfactory agreement with previously reported values. Other possible applications of the model are discussed.

The Radiolysis and Pyrolysis of Several Polyaromatic Compounds (open access)

The Radiolysis and Pyrolysis of Several Polyaromatic Compounds

The radiolysis of several polyaromatic compounds which might be used as coolant material in a reactor was investigated using both gamma and reactor radiation. The compounds selected were naphthalene, anthracene, naphthacene, pyrene, phenanthrene, 1, 2 benzanthracene, chrysene, triphenylene, 9, 10 dihydrophenanthrene, phenazine, 7, 8, benzoquinoline and m-phenanthroline, in addition to the uncondensed ring compounds, biphenyl, ortho, meta and para terphenyl and bibenzyl. Gas yields, percentage decomposition, percentage "high boiler" and number average molecular weights were determined. A correlation was found between radiation stability and electron affinity and singlet triplet excitation energies. The most stable compounds were the condensed ring compounds, naphthalene, pyrene, chrysene, phenanthrene and triphenylene.
