Abstract
A computer $program^{1}$ has been designed for the calculation of molecular vibration-rotation energy levels and eigenvectors for the case of first-order Coriolis resonance between a parallel band and a perpendicular band in molecules with symmetry $C_{3v}$. A previously presented computer $program^{2}$ in which one-parameter analyses were described has been refined by including further second-order terms. This refinement not only retains the localization of the perturbation within a given subband but also allows for a better fit to the experimentally observed perturbations in adjacent subbands. A perturbation in $\nu_{3} + \nu_{4}$ of $CH_{3}F$ observed by $Blass^{3}$ will be used as an illustration under the assumption that it is due to a Coriolis resonance with a nearby parallel band.
