The rotational spectrum of \(\mathrm{CH}_{3} \mathrm{OH}-\mathrm{CO}\) has been observed in the region \(7-18 \mathrm{GHz}\) with a pulsed-beam Fabry-Perot cavity Fourier-transform microwave spectrometer. In order to obtain detailed structural information the spectra of \(\mathrm{CH}_{3} \mathrm{OH}

The microwave rotational spectrum for the symmetric top, manganese pentacarbonylhydride, was measured in the 5-l 1 GHz range using a pulsed-beam, Fourier transform microwave spectrometer. For HMn(CO), we obtained A=E=907.9841( ) MHz andeqQ(Mn)=-44.22(2)MHz.ForDMn(CO)~,A=B=902.7682(3) MHzandeqQ(Mn)=-
The microwave spectrum of the van der Waals complex Ar-N2 has been investigated, t4N quadrupole coupling constants, rotational and centrifugal distortion constants, structural parameters and an estimate of the dipole moment have been obtained. A value for the ~4N quadrupole coupling constant for fre
