Moments de transition vibrationnelle des molecules diatomiques. Intensite des raies rovibrationnelles des bandes 0→2 et 0→3 et fonction dipolaire de CO

Abstract

General expressions for the radial wavefunctions and the rotationless matrix elements of the dipole moment for the transitions 0→0 to 0→4 are obtained using a fifth-power internuclear potential, a quartic dipole moment function, and third-order perturbation theory. Line intensities in the 0→2 and 0→3 bands of CO have been measured for pressures varying from 2 to 5 atm. Using the values of the vibrational transition moments | R 0 2| and | R 0 3| deduced from our measurements and the values of | R 0 0|, | R 0 1| and | R 0 4| previously given, we evaluate the coefficients M 0 to M 4 of the dipole-moment function for CO.
