摘要：

The high-resolution laboratory millimeter- and submillimeter-wave spectra of (CH3OH)-C-12 and (CH3OH)-C-13 have been extended to include transitions involving significantly higher angular momentum quantum numbers than studied previously. For (CH3OH)-C-12, the data set now includes 549 A torsional substate transitions and 524 E torsional substate transitions through J less-than-or-equal-to 24, exclusive of blends. For (CH3OH)-C-13 the data set now includes 453 A torsional substate transitions and 440 E torsional substate transitions through J less-than-or-equal-to 24, exclusive of blends. The extended internal axis method (IAM) Hamiltonian has been used to analyze the transitions to experimental accuracy. The molecular constants determined by this approach have been used to predict accurately the frequencies of many transitions through J = 25 not measured in the laboratory.
