1  Quantum chemistry study of the triplet nitrocompounds isomerization

Abstract: Photochemical oxidations of propylene by means of nitromethane and nitroethane were studied by UB3Lyp/6-31g in both the triplet and singlet states. It was studied the reaction paths giving propylene oxide. Gaussian03 was used to perform the calculations of the transition states of the reactions using QST2 and QST3 methods. Activation energies were calculated for every stage of the reactions. It was shown that the reaction proceeds mainly on the triplet potential surface energy.
