A Bond-Cell Method for Complex Molecules and Metals (open access)

A Bond-Cell Method for Complex Molecules and Metals

This technical report introduces "some approximations into the basic quantum mechanical theory" so that the theory of the covalent bond and the molecular orbital method "can be combined into one which will yield quantitative rather than qualitative binding energies and cohesive energies and also distinct energy levels and band structure." This approach will provide a common method "suitable to both solid state physicists and physical chemists, for calculating the energy levels in metals and complex molecules." This report also contains figures detailing the findings. (Quotations taken from introduction)

The Temperature Dependence of Birefringence in Irradiated Polyethylene (open access)

The Temperature Dependence of Birefringence in Irradiated Polyethylene

Technical report on a study where the birefringence of irradiated polyethylene was observed as a function of temperature. The data is consistent with a mechanism in which crosslinking limits the growth and annealing of crystallites. Crosslinks formed in material which was oriented at the time the crosslinks were formed, results in an oriented gel. This effect explains the birefringence and the persistence of nucleation sites at high temperatures.

A New Chlorophyll from Green Bacteria (open access)

A New Chlorophyll from Green Bacteria

The green photosynthetic bacteria are characterized by the presence of either chlorobium chlorophyll (bacterioviridin)-65o or chlorobium chlorophyll-66o (numerical designation based on the position of the red-absorption peak in ether) z. Most strains of Chlorobium contain chlorophyll-66o which has its major red peak between 74 ° and 75 ° m/~ in FiFo. KATZ AND WASSINK z first reported an additional minor absorption peak at 81o mF for Chlorobium limicola in vivo and a corresponding minor peak at 780 m F in ethanol extracts. LARSEN (Figs. 6-11 in ref. 3) also observed this 8Io-mF absorption band in another Chlorobium strain and a corresponding peak at 77 ° m/~ in acetone extracts. In strain L of C. thiosulfatophilum the minor red peak appears at 800 mF, clearly resolved from the main peak of chlorophyll-65o at about 725 m/~ (see refs. I, 4). We have observed the minor red peak once again in Chloropseudomonas ethylicum, strain 2K (refs. 5, 6), as a shoulder at about 81o mF on the side of the 75o-mF peak of chlorophyll-66o (ref. 7). The evidence presented in this paper indicates that the absorption peak appearing between 800 and 81o m/, in vivo does not belong to chlorophyll-65 o (or
