The radiation-induced transformations of small molecules at low temperatures play an important role in the interstellar, planetary and atmospheric chemistry. This work presents a review of our recent model studies on the radiation chemistry of releva

The primary radiation-induced processes in irradiated low-temperature pyrrolidinium- and piperidinium-type ionic liquids were investigated by EPR and optical absorption spectroscopy. A narrow singlet signal in the EPR spectra of irradiated ionic liqu

The spectral features and reactions of ion-radical intermediates produced from organic carbonates in low-temperature matrices were investigated by EPR spectroscopy and quantum-chemical calculations. It was shown that radical cations of diethyl carbon

The effect of X-ray irradiation on methanol molecules (CH3OH, CD3OH, and 13CH3OH) isolated in solid noble gas matrices (Ne, Ar, Kr, and Xe) was studied by FTIR spectroscopy at 6 K. CH2OH˙, H2CO, HCO˙ and CO were found to be the main degradation pro

The fate of excess electron produced in room temperature ionic liquids is an attractive and important topic, and its kinetics and optical absorption spectrum have been studied using pulse radiolysis and laser photolysis. However, there has been no cl

Structure of radical anions of “bridged” amidoesters MeOOC(CH2)nCONMe2 (n=0–3) generated by X-ray irradiation was investigated by EPR, optical absorption spectroscopy and quantum-chemical calculations. Amidoester-0 (n=0) has positive calculated

As found by EPR spectroscopy, the decay of methyl radicals in the test compounds upon X-ray irradiation at 77 K resulted from radical-center transfer rather than radical combination; the rate constants of decay of methyl radicals in polydimethylsilox

The strongest vibrational feature of a radical anion produced from the diacetyl molecule under radiolysis in a low-temperature dimethyl ether matrix has been characterized for the first time by the analysis of IR- and EPR-spectroscopic data supported

The radical anion resulting from electron capture by diacetonyl molecule has been characterized by EPR and optical absorption spectroscopy in glassy ether matrices at 77 K. In non-polar alkane glasses this species was not observed under the same cond

The grafting of the open-chain radicals of octamethylcyclotetrasiloxane (D4) to a block copolymer matrix is responsible for gelation in the test system under γ-irradiation at 10–40 kGy, as evidenced by viscometric, IR-spectroscopic and X-ray diffr
