QUARTIC FORCE-FIELDS OF RENNER-TELLER SYSTEMS (X2-PI) WITH 15 VALENCE-ELECTRONS
Résumé
For the 15 valence electron molecules BO2, CO2, CS2+, N3, NCO, and N2O+ the quartic force fields for both Renner-Teller components of the (X2PI) ground states are given. These potential expansions yield vibronic energies which agree to within 20 cm-1 with available experimental data. A set of effective molecular parameters has been derived and a comparison of the force fields for the different systems has been made.
