Title:Vibronic Analysis Of The Ã2 E′′ State Of No3 Radical
Author(s):Codd, Terrance Joseph
Contributor(s):Miller, Terry A.; Stanton, John F.
Subject(s):Radicals
Abstract:A moderate resolution spectrum of the $\widetilde{A}^2 E^{\prime\prime}$ state of the NO$_3$ radical has been obtained using jet-cooled cavity ringdown spectroscopy. The analysis of the vibronic structure of this spectrum has been undertaken using a quadratic Jahn-Teller Hamiltonian. All observed transitions have been assigned and unperturbed frequencies and Jahn-Teller coupling constants were determined by fitting the experimental spectrum using nonlinear least squares regression. We find evidence of strong Jahn-Teller coupling in this electronic state, particularly in the $\nu_3$ mode. These results are compared to electronic structure calculations including terms up to fourth order. Calculated and experimental spectra are presented and critically compared.
