✦ Synopsis

Frequencies of (445 \mathrm{CH}{3} \mathrm{OH}) rotational transitions between 1.5 and (6.5 \mathrm{THz}) have been measured with an accuracy of one part in (10^{9}). The far-infrared radiation used for the measurements was generated from the radiation of two (\mathrm{CO}{2}) lasers using a MIM diode as a nonlinear mixer. The high resolution and sensitivity of the spectrometer also enabled us to observe a series of forbidden (Q)-branch transitions ( (\Delta n=1) and (\Delta K=0) ) for (J=12) to 26 . 1994 Academic Press, Inc.
