The microwave spectra of three isotopomers of the complex of difluoromethane-xenon ((132)Xe, (131)Xe, (129)Xe) 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 (131)Xe nucleus in difluoromethane-(131)Xe have been precisely determined, chi(aa) = 0.941(4). chi(bb) = 0.642(4) and chi(cc) = -1.583(4) MHz, respectively.
