Microwave Spectrum of Formaldehyde I. K-type Doubling Spectra
Abstract
Microwave spectral lines for the direct transitions between the K-type doublets were measured from 3 kMc to 40 kMc for H2CO and for its isotopically substituted molecules HDCO, H2C13O and H2CO18. The observed spectra and the previously reported data for H2CO were analyzed by a digital computer by the use of Kivelson and Wilson’s method for the centrifugal distortion correction. The asymmetry parameter b and B-C were obtained for each isotopic species as follows: \includegraphics{dummy.eps} It was found that the observed frequencies fit well to those calculated from the centrifugal distortion constants which were derived by the vibration-rotation interaction theory.
