The unimolecular dissociation of HCO. V. Mixings between resonance states
The unimolecular dissociation of HCO in its ground electronic state is considered. By performing calculations (filter diagonalization, absorbing potential) for nonzero angular momentum quantum numbers, it is demonstrated how mixings with near-by "background" states affect the linewidths of the narrower resonance states. This explains qualitatively the theoretically as well as experimentally observed behavior of the linewidth as a function of the vibrational quantum numbers.
