The microwave spectra of three isotopomers of the complex of difluoromethane–xenon (132Xe, 131Xe, 129Xe) have been studied by supersonic jet Fourier transform microwave spectroscopy. A general improvement of the fittings has been obtained with respect to a previous millimeter wave free jet investigation [W. Caminati, J. Phys. Chem. A. 110 (2006) 4359]. In particular, the nuclear quadrupole coupling constants of the 131Xe nucleus in difluoromethane–131Xe have been precisely determined, χaa = 0.941(4), χbb = 0.642(4) and χcc = -1.583(4) MHz, respectively.

Abstract
The microwave spectra of three isotopomers of the complex of difluoromethane–xenon (132Xe, 131Xe, 129Xe) have been studied by supersonic jet Fourier transform microwave spectroscopy. A general improvement of the fittings has been obtained with respect to a previous millimeter wave free jet investigation [W. Caminati, J. Phys. Chem. A. 110 (2006) 4359]. In particular, the nuclear quadrupole coupling constants of the 131Xe nucleus in difluoromethane–131Xe have been precisely determined, χaa = 0.941(4), χbb = 0.642(4) and χcc = -1.583(4) MHz, respectively.File in questo prodotto:
