Abstract
The global modeling of 12C32S2 line positions in the 240 – 12 000 cm−1 region has been performed using the non-polyad model of effective Hamiltonian. The effective Hamiltonian parameters were fitted to the measured line positions collected from the literature. The fitted set of 99 effective Hamiltonian parameters allowed reproduction of more than 13 000 measured line positions with the dimensionless weighted standard deviation of 1.65. The root-mean-square of errors of the fitted high-resolution rotation-vibration line positions in the 240 - 466 cm−1 range is 0.0013 cm−1. A comparison of the calculated line positions based on the fitted model with HITRAN2020 is presented and discussed.
