Electric dipole moment function of H 79Br

Abstract

An anharmonic potential function with 11 parameters was used in numerically solving the radial Schrödinger wave equation to obtain potential constants of hydrogen bromide molecule, H 79Br. Vibration–rotation energy states up to the vibrational level v=8 and the corresponding wavefunctions were generated. The dipole moment matrix elements, M 0 v′(m) , were evaluated using the experimentally determined line strengths. The dipole moment coefficients, M 0, M 1,…, M 8, were then calculated from these matrix elements and wavefunctions.
