Abstract

A bank of spectral line parameters of the principal isotopologue of the hydrogen sulfide molecule (H₂³²S) is presented. The databank is based on the global simulation of line positions and intensities of this molecule within the method of effective operators. Parameters of the global effective Hamiltonian and effective dipole moment operator were derived from their fitting to the line positions and intensities observed, respectively, which were taken from the literature. The databank covers the 552.76–8424.32 cm⁻¹ spectral range and includes the calculated values of the following spectral line parameters: line position and intensity, energies of lower and upper states, Einstein coefficient for the spontaneous emission, and the statistical weights of the lower and upper states. The intensity cutoff was chosen equal to 10⁻²⁸ cm/molecule at T = 296 K. In total, the databank contains about 88 thousand lines. This databank is deployed on the website of V.E. Zuev Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences (ftp://ftp.iao.ru/pub/H2S/).

H 2 S分子的谱线参数库

摘要

给出了硫化氢分子（H ₂ ³² S）的主要同位素同位素的光谱线参数库。数据库基于有效算子方法中该分子的线位置和强度的全局模拟。全局有效哈密顿算子和有效偶极矩算子的参数分别来自它们与所观测到的线位置和强度的拟合度，这是从文献中得出的。数据库覆盖552.76–8424.32 cm ^-1光谱范围，包括以下光谱线参数的计算值：线位置和强度，上下状态的能量，自发发射的爱因斯坦系数以及上下状态的统计权重。在T = 296 K时，强度截止选择为等于10 ^-28 cm /分子。数据库总共包含约8.8万行。该数据库部署在俄罗斯科学院西伯利亚分校VE Zuev大气光学研究所的网站上（ftp://ftp.iao.ru/pub/H2S/）。
