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.

二氧化硫同位素的振动能级
对于SO2分子的5种同位素:32S16O2、34S16O2、33S16O2、32S18O2和32S16O18O,利用同位素取代理论的基本关系,拟合得到了有效振动哈密顿量的参数。由拟合得到的振动常数再现了对称同位素在0.025 cm-1范围内的实验振动能级。将得到的振动能级与变分计算结果进行了比较,并对93个振动态的量子数进行了修正。

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.
