PRECISE LABORATORY MEASUREMENTS OF METHANOL ROTATIONAL TRANSITION FREQUENCIES IN THE 5-GHZ TO 13-GHZ REGION

Rotational transitions for CH3OH were measured in the 5-13 GHz range with a precision and accuracy of a few kilohertz or less using a Flygare-Balle type pulsed-beam Fourier transform microwave spectrometer. The accurate center frequencies for transitions measured should be useful in determining accurate Doppler shifts and making positive molecule identification in radio astronomy.
