摘要：

Single crystals of CH3CO2H, CHCO2D, CD3CO2D and CD3CO2Li . 2D2O have been irradiated with X-rays and investigated by ESR spectroscopy with the purpose of comparing the fragmentation pattern of the molecular anion radicals. CD3CO Was identified as the radical product in the decay of CD3CO2D- in CD3CO2D, and CO2-was similarly identified in the decay of CD3CO22- in CD3CO2Li . 2D2O, confirming an earlier observation [LoBrutto, R., Budzinski, E. E. and Box, H. C. J. Chem. Phys. 73 (1980) 63491. The mechanism is discussed.
