Title:Ab Initio Calculation For The Spin-orbit Splittings Of The Nitrate Radical (no3)
Author(s):Stanton, John F.
Contributor(s):Cheng, Lan
Subject(s):Radicals
Abstract:In this work we present a quantum-chemical calculation of the electronic spin-orbit splittings for the spatially degenerate low-lying E$^\prime$ and E$^{\prime\prime}$ states of the nitrate radical (NO$_3$). The calculation is based on a degenerate perturbation theory using scalar-relativistic equation of motion ionization potential (EOMIP) coupled-cluster singles and doubles (CCSD) wave functions together with spin-orbit matrix elements constructed in the framework of exact two-component (X2C) theory. The computed SO splittings are discussed in view of recent experiments by Babu et al. for the B$^2$E$^\prime$ state and Miller et al. for the X$^2$A$_2^\prime$ state. Calculations of splittings based on vibronic, rather than simply electronic, wave functions are also discussed.
