Research output: Contribution to journalArticlepeer-review

H and D photofragments, produced via vibrationally mediated photodissociation of jet-cooled C2HD allowed measurement of vibrational and vibronic excitation action spectra of the parent as well as H and D Doppler profiles. The initial vibrational preparation at energies around 9700 cm-1 enhanced C-H and C-D bond cleavage for transitions from an initially excited bent state to the upper à state, rather than from a close lying state containing three C-H stretch quanta, due to favorable Franck-Condon factors for the former. The bound region of the A state was accessed, resulting in non-adiabatic dissociation and slight preferential C-H over C-D bond cleavage.
