Abstract

AbstractPhenoxide anions (PhO−) and phenoxy radicals (PhO) were generated by the electron bombardment of a phenol/argon sample during matrix deposition. Further irradiation of the matrix sample at 365 nm led to the detachment of the electron from PhO− and afforded its neutral counterpart PhO in solid Ar. In a separate experiment, the photolysis of a phenol/Ar matrix at 160 nm mainly afforded PhO, phenyl (Ph) radicals, and various open‐chain ketenes, but no PhO−. The Infrared (IR) lines of PhO− were assigned on the basis of the observed photochemical behaviors and the prediction of the vibrational wavenumbers with the corresponding IR intensities predicted by the B3LYP/aug‐cc‐pVTZ theory.
