Der Intensitätsverlauf im reinen Rotations-Raman-Spektrum von CO2 und N2O unter Berücksichtigung des 0110-Niveaus / Intensity Distribution in Pure Rotational Raman Spectra of CO2 and N2O Taking into Account Contributions from the 0110 State

Abstract

Abstract The pure rotational Raman spectra of carbon dioxide and nitrous oxide have been recorded with argon laser excitation and a resolution of about 0.2 cm-1. As was found previously for acetylene, also for these molecules R-branch transitions in the excited II-states could be resolved clearly up to J=9. The relative intensity distribution has been analyzed quantitatively according to formulae derived previously. It turns out that the experimental intensity distribution is well reproduced by taking into account only the component of the anisotropic part of the polarizability tensor. Higher order contributions arising from the components could not be detected.
