Abstract
For five isotopologues of the SO2 molecule: 32S16O2, 34S16O2, 33S16O2, 32S18O2, and 32S16O18O, parameters of the effective vibrational Hamiltonian are derived from fitting to the available experimental data, as well as using the basic relations of the isotope substitution theory. Vibrational constants obtained from the fit reproduce the experimental vibrational energy levels within 0.025 cm–1 for symmetric isotopologues. The obtained vibrational energy levels are compared with the variational calculation, and the quantum numbers for 93 vibrational states are corrected.
期刊介绍：
Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
