Resonance Raman (RR) spectra were measured for the cation radical of bacteriochlorophyli a in acetone, methanol, dichloromethane and mixed solvents of acetone and methanol. The ring-breathing (C~-C m stretching) frequency of the radical (abbreviated as v~ +) was observed at 1601 cm-i in acetone (for

A~tract--The photo-oxidation of butadiene rubber (BR) was studied in detail using films of a commercially available material, containing 33% cis-l,4-, 56°/o trans-l,4and 12% 1,2-vinylic units. The spectral data of the products showed that during photo-oxidation the following functional organic group

The yields and spatial distribution of the products arising from the in source oxidation of 50 lm LDPE films induced by 60-Co gamma radiations and by 300 kev electrons have been investigated as a function of the dose rate. The dose rate was found to have a strong influence on the reaction, the hydro
