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 |R02| and |R03| deduced from our measurements and the values of |R00|, |R01| and |R04| previously given, we evaluate the coefficients M0 to M4 of the dipole-moment function for CO. |
