Vibration Rotation

Methods for determining the true widths of lines in simple vibration-rotation bands have been considered, and a procedure has been devised for studying the effect of added gases upon the line widths in the fundamental vibration bands of deuterium chloride and carbon monoxide

The absolute intensity A2–0 of the 2–0 band of carbon monoxide has been measured with helium and argon as pressure broadening gases at pressures up to 600 amagat. A separate band intensity value has been derived from the measurements of several P-branch line intensity data and the Herman–Wallis formula. The best value obtained is A2–0 = (2.11 ± 0.08) cm−2 amagat−1. The square of the rotationless matrix element, [Formula: see text] has been found to be (4.39 ± 0.02)10−5 D2, as estimated from the measured line intensity values.

Line Positions

A collection of 10 866 of the most precise ground-state (X1Σ+) vibration–rotational and pure rotational line positions of four carbon monoxide isptopomers (12C16O, 12C18O, 13C16O, and 13C18O) is employed simultaneously in a direct determination of the radial Hamiltonian operator in compact analytical form. The 22-parameter isotopically self-consistent operator takes full account of the Born–Oppenheimer breakdown and its quantum-mechanical eigenvalues represent all the available spectroscopic line positions of CO isotopomers to within the experimental uncertainties. Rayleigh–Schrödinger perturbation theory is employed to calculate quantum-mechanical molecular constants of rotation (Bν – Mν) for nine common isotopomeric forms of CO. Together with the quantum-mechanical vibrational eigenvalues these are fully consistent with the exact eigenvalues obtained by direct solution of the radial wave equation. The set of constants is expected to provide an accurate prediction of line positions of CO isotopomers that have not yet been experimentally observed.
