The effect of rotation-vibrational interaction on the line intensities in the optical spectra of diatomic molecules
Using perturbation calculation simple relations have been received that make possible to evaluate the appearance of rotation-vibrational interaction in the line intensity of gaseous diatomic molecules from a sufficient number of experimental data. The connection between the rotational temperature determined from the optical spectra neglecting rotation-vibrational interaction and the real rotational temperature of the gas has been found.
