| Abstract: | Numerical methods for the analysis of high-resolution infrared spectra of symmetric top molecules perturbed by Coriolis interactions between degenerate and nondegenerate vibrational levels are discussed in the second order of approximation. Application to the high-resolution infrared spectra of the AsH3 molecule in the region of the fundamentals ν1, ν3 and ν2, ν4 yields considerably improved values of the molecular constants of AsH3, including the band origins rotational constants, Coriolis coupling constants, centrifugal distortion constants, and the parameter of the K-type doubling effect. |
