Calculation of resonance states of non-rotating HOCl using an accurate ab initio potential

Complex L-2 calculations for selected resonance states of non-rotating HOCl are reported using a recently developed, accurate ab initio potential ener gy surface [S. Skokov, J. M. Bowman and K. A. Peterson, J. Chem. Phys., 199 8, 109, 2662]. The calculations are carried out for energies up to 10 kcal mol(-1) above the dissociation limit with a truncation/recoupling method an d a Chebyshev propagation/filter diagonalization. Final rotational states d istribution of the OH fragment are also reported for two contrasting resona nces, using the truncation/recoupling method.
