PHOTODISSOCIATION DYNAMICS OF HCOOH(A)

Journal article

The technique of Doppler-resolved, polarised LIF spectroscopy has been employed in a study of the energy and momenta disposal in the OH fragments generated via photodissociation of HCOOH (Ã 1A″) at 225 nm. The majority of the excess energy resides in fragment translation (≈ 78%) and internal excitation of the HCO fragment (≈ 12%). An analysis of the Doppler-resolved profiles reveals that OH rotational excitation (for N″ ≈ 6) is generated primarily by out-of-plane C-OH torsional motion in the excited parent molecule. The results are compared with those for the OH fragments generated via photodissociation of the iso-electronic molecule HONO(Ã 1A″). © 1988.
