Ultraviolet absorption spectra of CdCH3, ZnCH3, and TeCH3

Abstract

Ultraviolet absorption spectra were recorded for the transient radicals CdCH3, ZnCH3, and TeCH3 produced in the flash photolysis of the appropriate dimethyl metals. For CdCH3 and ZnCH3 two systems were observed and assigned to the two transitions à 2E← x̃2 A1 and B̃ 2E← x̃2 A1. For the TeCH3 radical only one system was observed which was assigned to the B̃← x̃ transition. The progressions in the spectra are assigned to the upper state carbon-metal stretching vibration (ν′3) and CH3 symmetric deformation vibrations (ν′2).
