Abstract
The radiothermoluminescence (RTL) spectra of organic frozen compounds such as methanol, acetone and several hydrocarbons are presented and discussed. Some evidence concerning the negative species responsible for RTL emission and the mechanism of excited-state formation is given. A satisfactory correlation between the temperature of RTL peaks and phase transition points has been found for the methanol-water system as well as for acetone. Additional experimental results are provided concerning the tunnelling hypothesis as a best approach to the kinetics of electron decay in 3-MP glass in the presence of biphenyl and for isothermal radioluminescence (IRL) decay observed at 77 K in such systems as acetone, ethyl acetate and methylcyclohexane. The temperature and viscosity effects on electron decay in organic glasses are pointed out.
