Description
Summary:The dipole moment function of hydrogen chloride has been determined from the combined data of dipole moments, transition moments, and Herman-Wallis factors for HCl and DCl, which include the recent measurements of vibration-rotation transitions up to the v = 7 level. The direct numerical diagonalization of vibration and vibration-rotation Hamiltonian matrices has been used to obtain the radial part wavefunctions. The sextic and septic dipole moment functions thus obtained give much improved overall fit to the experimental data. The results also agree well with those obtained from the RKR procedure. Some of the features of the present dipole moment functions are discussed.
