Vibrational predissociation in HD-HF

Abstract

Total and partial decay widths are presented for vibrational predissociation of HD-HF for total angular momentum J=0 and for the dissociation process HD-HF(v=1) → HD(v=1) + HF(v=0), which is the dominant decaying channel. An absorbing boundary condition Green function method is employed in the numerical calculation for the decay width. The lifetime of the complex is determined from our calculation to be about 280 ps which is much smaller than that of D2HF and of H2HF obtained in our previous calculations. The rotational state distribution of the fragments shows that about 77% of the dissociation energy goes into rotations of the fragments with the dominant channel being HD(j=2) + HF(j=0), which accounts for about 70% of the rotation population.
