Single Vibronic Level Photochemistry of Formaldehyde (H2CO singlet A2): I. Radiative and Non-Radiative Transitions.
Abstract
Fluorescence decay times and fluorescence emission quantum yields from various single vibronic levels of the first excited singlet state of H2CO (singlet A2) have been measured. Radiative and non-radiative lifetimes of the single vibronic levels have been determined. The stronger promoting vibrational mode for the radiative transition is the asymmetric stretch mode rather than the out-of-plane bending mode. The latter mode, however, is a promoting mode for the non-radiative transition. As much as a factor of 40 variation in the radiative lifetime values is observed for the variety of vibrational states studied.
