Extended wavenumber domain collision‐induced Raman scattering by gaseous neon

A joint experimental and theoretical study of depolarized, I∥(ν), binary collision-induced Raman scattering spectra by gaseous room-temperature neon was made. An absolute-unit calibration of the measured scattering cross-sections permitted a straightforward comparison of the data with cross-sections obtained with quantum mechanics. A broad detuning domain was explored, reaching the far spectral wing at wavenumber shifts ν almost twice as large as those probed so far. A novel ab initio symmetry adapted perturbation theory pair-anisotropy model was employed, yielding spectra in agreement with the experiment. Copyright © 2003 John Wiley & Sons, Ltd.
