✦ Synopsis

Over 20 new millimeter-wave transitions of the 12 C 16 O dimer are measured in the 77-to 186-GHz range using a coaxial pulsed jet spectrometer. Sixteen of these are unambiguously assigned using millimeter-wave combination differences, and three are tentatively assigned using infrared data. Some new or revised assignments of previously observed transitions are also proposed. The new results serve to locate a number of levels of the dimer for the first time with "microwave" (Υ‡0.1 MHz) accuracy. Such accuracy is important not just for its own sake, but also because it facilitates future assignments in the CO dimer spectra using precise combination differences.

The millimeter-wave spectrum of the normal isotope of the CO dimer, ( 12 C 16 O) 2 , has been systematically surveyed in the regions 75-105 and 131-174 GHz, with additional measurements covering the entire 60-176 GHz range. By combining these results and using the technique of combination difference

The ground state rotational spectrum of CD3OH has been revisited in the millimeter-wave range. A total of 216 transition frequencies have been measured and assigned in the 117-179 GHz spectral range, including about 40 transitions previously reported. The spectrum was recorded at the Justus-Liebig U
