Millimeter Wave Rotational Spectrum and Centrifugal Distortion

Intensive studies have been carried out on the rotational spectra of various isotopic species of ketene, H2C = C = 0 , since 1950 [ 1 6 ] . The centrifugal distortion analysis of ketene [3, 4 ] , together with information from additional infrared data [3, 5 ] , enabled Mallinson and Nemes [6] to reevaluate the molecular force field for ketene. Recently, microwave investigations on the higher ho...

Millimeter-Wave Spectrum of the NO Dimer

The pure rotational spectrum of the NO dimer, (14N16O)2, has been studied in the 225-400 GHz millimeter-wave region by means of direct absorption in a supersonic jet expansion. Previously, only 4 rotational transitions of (NO)2 had been measured in the microwave region. To these, we have added 66 new millimeter-wave transitions with values of J ranging from 4 to 16 and of Ka from 2 to 7. Most t...
