“…They show similar behavior upon photolysis at 365 and 160 nm (Figure S2) and may be attributed to the same carrier. Based on our previous studies on electron bombardment of matrix samples at low energy, the observed primary products include ionic precursors and/or fragments missing a hydrogen atom. − Therefore, we expect the carrier of these unknown lines to have a backbone similar to that of acetone. We calculated the vibrational wavenumbers of the neutral and ionic forms of possible species and summarized the results in Tables S1–S7.…”

The 1-methylvinoxy radical (1-MVO) is an important intermediate in the combustion and tropospheric reaction of OH. However, the vibrational structures of this species and its anionic form, 1-methylvinoxide anion (1-MVO − ), are not fully known. Thus, in this study, we obtained the infrared (IR) absorption spectra of 1-MVO and 1-MVO − trapped in a solid Ar matrix. 1-MVO − anions were produced by electron bombardment during matrix deposition of Ar containing a small amount of acetone. The anions were destroyed upon irradiation at 675, 365, and 160 nm, although the formation of 1-MVO was only observed upon irradiation at 675 nm. The assignment of the IR bands of 1-MVO − and 1-MVO was based on the expected chemistry upon photoexcitation and comparison of line wavenumbers, relative IR intensities, and D-isotopic shift ratios with those predicted at the B3LYP/ aug-cc-pVTZ level of theory.

Phenoxide 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.
