Abstract

Structural and potential constants obtained from infrared data are used with the theory of vibration-rotation interaction to obtain rotational and distortion parameters for the molecules H2O, D2O, and HDO; transition frequencies calculated using these parameters are compared with those observed in the microwave region, and, in the case of HDO Q-branch lines, a simple relation between the two sets is obtained. The validity of approximation theories as applied to HDO Q-branch transitions is discussed. Methods of analyzing the observed spectrum of HDO are described, and so-called "observed" parameters for this molecule are obtained; the rotational constants are found to be a=7.0396±0.0005×105 Mc/sec, b=2.7360±0.0005×105 Mc/sec, c=1.9186±0.0005×105 Mc/sec, κ=0.6841±0.0002.
