Abstract:

The excited vibrational states of the ozone molecule are studied using the vibrationally self-consistent field-configuration interaction (SCF-CI) procedure. In order to reproduce the observed vibrational band origins well, the potential energy surface for the electronic ground state of O3 is optimized using the recently observed vibrational band origins up to 4400 cm-1. The root-mean-square error of this fitting for the 30 observed vibrational energy levels is 0.47 cm-1. All the calculated band origins are within 1.0 cm-1 of the observed values.
