The intensities of all rovibrational electric quadrupole absorption lines in 16O2 (X3Σg), for which the vibrational quantum number is v35 and the total angular momentum quantum number is J40, are calculated in the intermediate coupling using a new ab initio quadrupole moment curve of the ground electronic state of O2. The calculated values agree with those available in the HITRAN database, which at present includes, for quadrupole transitions, only the 1-0 fundamental vibrational band of 16O2 (X3Σg). We therefore recommend using the intensities of the vibrational overtones and hot bands reported here in updating the HITRAN database for O2 in the upcoming 2024 edition.

用新的从头计算四极矩曲线计算的 16O 中所有精细结构分辨的振动电四极吸收线的强度[公式省略]([公式省略])



在振动量子数为 v≤35 且总角动量量子数为 J≤40 的 16O2 (X3Σg-) 中,所有振动电四极吸收线的强度是在中间耦合中使用 O2 的接地电子态的新从头四极矩曲线计算的。计算值与 HITRAN 数据库中可用的值一致,目前对于四极子跃迁,仅包括 16O2 (X3Σg−) 的 1-0 基波带。因此,我们建议在即将到来的 2024 年版中更新基于 O2 的 HITRAN 数据库时,使用此处报告的振动泛音和热带的强度。
