Computation of H2O Quadrupole Moment Matrix Elements for Pressure Broadening Calculations,
Abstract
Recent tunable laser measurements indicate that theoretical linewidths, calculated for H2O self-broadened transitions and based solely on the effects of dipole-dipole collisions, are too small at high and intermediate J values. This suggests neglect of other important scattering mechanisms, such as dipole-quadrupole interactions. This report discusses computational procedures necessary to obtain quadrupole moment matrix elements for H2O and other asymmetric rotor molecules. Computer programs to obtain these matrix elements have been constructed and are presently operational. Numerical results for some low J quadrupole transitions are presented in Appendix B of the report. (Author)
