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 …

Abstract: "A measurement was made of the dissociation of vibrationally-excited H2+ ions by photons having quantum energy in the vicinity of 4 e.v. The calculated cross section from theory is 3 x 10-(-18) cm-2. The experimental result is 10-(-17) cm-2; a factor of 10 uncertainty is present because the photon intensity was unknown by that factor."

Gravitational-Electromagnetic Torus Models of the Elementary Particles (open access)

Gravitational-Electromagnetic Torus Models of the Elementary Particles

Abstract: "A torus model of the elementary particles is suggested in which the electron and proton are made stable by gravitational forces derived from the electromagnetic field. It is suggested that the gravitational forces for the unstable particles, presumably the mesons, are not sufficient to keep the torus from expanding in the direction of its large radius. Rest energy zero can be achieved, presumably for photons and neutrons, when the gravitational energy and electromagnetic field energy are equal in magnitude. The manner in which these models can exhibit spin, magnetic moment, wave length, and phase velocity is indicated. The origin of nuclear forces from an electromagnetic basis is indicated."
