The microwave spectrum of methyl formate has been observed in the 7-200 GHz region, and new 437 lines have been assigned to the first excited A torsional substate. Both excited state lines and ground state lines reported previously were analyzed simu

Microwave sidebands of CO2 laser lines were used as an infrared source in infrared microwave double resonance spectroscopy and infrared saturation spectroscopy to study the C -O stretching fundamental band of methanol. In the former application, rota

We have observed rotational transitions of ethylmethyl ether (CH3CH2OCH3) in the 24-110 GHz frequency range. We newly assigned the transitions of four Q-branch series for J=1-38 with Ka=0-5 and six R-branch series of b-type transitions for J=7-37 wit

Torsion–rotation parameters have been calculated for 12C- and 13C-methanol isotopomers of CD3OH with 16O, 17O, and 18O from potential energy surfaces for methanol using an approach developed by Duan and Takagi [Phys. Lett. A 207 (1995) 203]. With t
