Direct observation of preferential bond fission by excitation of a vibrational fundamental: Photodissociation of HOD (0, 0, 1) Academic Article uri icon


  • The 193 nm photodissociation of individual rotational levels of HOD molecules excited with one quantum of O–H stretching vibrational energy is described. Stimulated Raman excitation and coherent anti‐Stokes Raman scattering are used to prepare and detect, respectively, the (0, 0, 1) vibrationally excited HOD. The OD and OH fragments are detected by laser induced fluorescence. The photodissociation of the HOD (0, 0, 1) molecules yields at least three times more OD than OH.
