Abstract
With the use of a /b Q/-switched spin-flip Raman laser rovibrational lines of ethylene in the 2000 cm/sup -1/ region have been measured with an accuracy of the order of 0.005 cm/sup -1/. On the basis of these data and previous conventional high resolution spectra an analysis of nu /sub 7/+ nu /sub 8/, nu /sub 4 /+ nu /sub 8/ and nu /sub 10/+ nu /sub 8/ has been performed. The results permit calculation of the harmonic and anharmonic contributions to the rotational constants of nu /sub 7/ and nu /sub 7/+ nu /sub 8/, and allow the nu /sub 8/ rotational constants to be estimated.AnglaiKeywords
