Photodissociation of HOD via the (C)over-tilde(1)B(1) State: OD/OH Branching Ratio and OD Bond Dissociation Energy

Photodissociation of jet-cooled hod via the (c) over tilde state around 124 nm has been studied using the h(d)-atom rydberg tagging time-of-flight technique. rotational state resolved action spectrum and the product translational energy distribution spectra have been recorded for both d+oh and h+od dissociation channels. product channel oh/od branching ratios for the individual (c) over tilde-(x) over tilde rotational transition have been determined. a comparison is also given with the (b) over tilde-(x) over tilde and (a) over tilde-(x) over tilde transitions. in addition, the dissociation energy of the od bond in hod has been determined accurately to be 41751.3 +/- 5 cm(-1).
