LINE-INTENSITIES IN THE NU(2) BAND OF (H2SE)-SE-80

Using a high-resolution Fourier transform spectrum of hydrogen selenide in natural abundance, about 350 intensities of lines belonging to the nu2 band of (H2Se)-Se-80 have been measured. These intensities were least-squares fitted, leading to the determination of the vibrational transition moment of this band as well as of its first-order rotational corrections. The first derivative of the dipole moment with respect to the q2 normal coordinate was found to be partial derivative mu(x)/partial derivative q2 = (0.4168 +/- 0.010) x 10(-1) D.
