Experimental determination of the 1Σ+ state electric dipole moment function of carbon monoxide up to a large internuclear separation

Abstract

Experimental intensity information is combined with numerically obtained vibrational wave functions in a nonlinear least-squares fitting procedure to obtain the ground electronic state electric dipole moment function of carbon monoxide valid in the range of nuclear oscillation (0.87–1.91 Å) of about the V = 38th vibrational level. Vibrational transition matrix elements are computed from this function for ΔV = 1, 2, 3 with V ≤ 38.
