摘要：
The microwave spectra of three isotopomers of the complex of difluoromethane-xenon (Xe-132, Xe-131, Xe-129) 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 (Caminati, 2006) [12]. In particular. the nuclear quadrupole coupling constants of the Xe-131 nucleus in difluoromethane-Xe-131 have been precisely determined, chi(aa) = 0.941(4). chi(bb) = 0.642(4) and chi(cc) = -1.583(4) MHz, respectively.
