Transition moments, band strengths, and line strengths for NaH

Electronic transition moments, as functions of internuclear separation, are calculated for the A1Σ+ → X1Σ+, B1Π → X1Σ+, B1Π → A1Σ+, c3Σ+ → a3Σ+, b3Π → a3Σ+, and b3Π → c3Σ+ transitions in NaH from ab initio molecular wavefunctions. Reduced line strengths, band strengths, band oscillator strengths, an...

Description
Summary:Electronic transition moments, as functions of internuclear separation, are calculated for the A1Σ+ → X1Σ+, B1Π → X1Σ+, B1Π → A1Σ+, c3Σ+ → a3Σ+, b3Π → a3Σ+, and b3Π → c3Σ+ transitions in NaH from ab initio molecular wavefunctions. Reduced line strengths, band strengths, band oscillator strengths, and band Einstein coefficients are calculated for the observed A1Σ+ → X1Σ+ transition, and are compared to experimental band intensities. Also calculated are Franck–Condon factors and R centroids, and the effects of various approximations used in treating experimental data are analyzed.
