Abstract

¹⁶O¹²C¹⁷O is the fourth most abundant isotopologue of carbon dioxide. As part of this study, a total of 16 223 rovibrational transitions, 9822 unique ones, measured for the ground electronic state of CO

_{2}

, were collected from 31 articles, corresponding to the limited wavenumber range of 634–12 727 cm⁻¹. The measured transitions span the polyads

P = 0 - 17

, where

P = 2 v_{1} + v_{2} + 3 v_{3}

, and

v_{1}

v_{2}

, and

v_{3}

are the normal-mode quantum numbers corresponding to the symmetric stretch, linear bend, and antisymmetric stretch motions. Following a careful validation of the compiled rovibrational transitions data, a set of 5036 empirical rovibrational energy levels has been determined. Comparison of the empirical energy-level data of this study with those in the CDSD-296 and NASA Ames-2021 line lists shows good general agreement.

16O12C17O高分辨率旋转振动光谱的MARVEL分析

16O12C17O是第四丰富的二氧化碳同位素物。作为本研究的一部分，从31篇文章中收集了16 223个旋转振动跃迁，其中9822个是唯一的，用于测量CO2的基电子态，对应于有限波数范围634-12 727 cm−1。测量的跃迁跨越多边形P=0−17，其中P=2v1+v2+3v3, v1， v2和v3是对应于对称拉伸，线性弯曲和反对称拉伸运动的正模量子数。经过对汇编的旋转振动跃迁数据的仔细验证，确定了一组5036个经验旋转振动能级。将本研究的经验能级数据与CDSD-296和NASA Ames-2021线表中的数据进行比较，结果显示出良好的总体一致性。
