Abstract
Ground state radical dissociation pathways of HDCO were investigated. Frequencies of rovibrational lines from a variety of vibrational bands of the first singlet excited state over a broad excitation energy range were determined and subsequently used to excite singly deuterated formaldehyde, HDCO. Translational energy release of H and D atoms measured by velocity map imaging was then used to determine accurate threshold energies of 30,448 ± 5 cm−1 for H + DCO and 30,949 ± 3 cm−1 for D + HCO.
