Electric dipole moment function of (HBr)-Br-79

An anharmonic potential function with 11 parameters was used in numerically solving the radial Schrodinger wave equation to obtain potential constants of hydrogen bromide molecule, (HBr)-Br-79. Vibration-rotation energy state s up to the vibrational level upsilon = 8 and the corresponding wavefunctio ns were generated. The dipole moment matrix elements,. M-0(upsilon ')(in), were evaluated using the experimentally determined line strengths. The dipo le moment coefficients, M-0, M-1,..., M-8, were then calculated from these matrix elements and wavefunctions. (C) 2001 Elsevier Science Ltd. All right s reserved.
