Thermal deactivation of trapped excitons in 4,4'-dimethylbenzophenone

Thermal deactivation of trapped excitons in 4,4'-dimethylbenzophenone. Bonno, B.; Laporte, J. L. 611-97-2 are also occured in this study.; Rousset, Y. (Lab. Opt. Mol., Univ. Reims, Reims 51062, Fr.). J. Lumin., 28(4), 443-50 (English) 1983. CODEN: JLUMA8. ISSN: 0022-2313. DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) Section cross-reference(s): 22 Spectral and time analyses of the phosphorescence emission of pure 4,4'-dimethylbenzophenone at 77-150 K are given. The trapping and detrapping rate consts. were obtained from a kinetic model involving a trap located at 1000 cm-1. The order of magnitude of the diffusion coeff. of triplet excitons was deduced. .

Utility of pulse nuclear magnetic resonance in studying protons in coals

Utility of pulse nuclear magnetic resonance in studying protons in coals. Gerstein, B. C.; Chow, C.; Pembleton, R. G.; Wilson, R. C. (Ames Lab., Iowa State Univ., Ames, Iowa, USA). J. Phys. Chem., 81(6), 565-70 (English) 1977. CODEN: JPCHAX. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 73 ESR, pulse NMR, and multiple pulse NMR were used to study free radical concns., and the extent to which protons in coals are characterized by damping consts. under specific radio-frequency pulse sequence in vitrains and selected model arom. compds. ESR measurements confirmed previously obsd. correlations between free radical content and C content. 90-12-0 and 611-97-2 which are cas registry numbers of substances are two of reagents here. Electron g factors varying from 2.0025 to 2.0028 are consistent with assignment of free radicals to arom. ring systems. .
