THE SUBMILLIMETER-WAVE ROTATIONAL SPECTRUM OF FLUOROFORM - ANALYSIS OF THE KAPPA = 3 LINE DOUBLING

The millimeter- and submillimeter-wave spectra of CHF3, v = 0, v3 = 1, 13CHF3, v = 0, CDF3, v = 0, v = 1, v3 = 1, and 13CDF3, v = 0 have been observed and accurate rotational and centrifugal distortion constants have been derived from their analysis. The splitting of the K = 3 lines of CHF3 and CDF3 has been observed for high-J values and the splitting constant h3 has been determined. The J dependence of the h3 coefficient was also pointed out. © 1994 Academic Press, Inc.
