Fourier-transform spectra of room-temperature carbon dioxide compressed to pressures up to 19 atm reported previously are re-analyzed to obtain weak line-mixing parameters and a representation of full line mixing for transitions observed in the P- and Q-branches of the 11101 ← 00001 (Π ← Σ) band centered at 2076.86 cm−1. Similar analyses for the R-branch transitions are prevented by strong Coriolis resonances that nearly completely transfer the intensities of R-branch transitions to the P-branch. The weak line mixing coefficients are retrieved experimentally and are modeled using the Exponential Power Gap scaling law. Another modeling is performed with an Energy-Corrected-Sudden type approach making use of a symmetric relaxation matrix satisfying all basic relations. Comparisons of experimental and calculated parameters with results available in the literature are presented and discussed.

11101←00001 二氧化碳带中线混合效应的表征,压力高达 19 个大气压

对先前报道的压缩至 19 个大气压的室温二氧化碳的傅立叶变换光谱进行重新分析,以获得弱线混合参数和在 P 和 Q 分支中观察到的转变的全线混合表示11101 ← 00001 (Π ← Σ) 带中心在 2076.86 cm -1. 强科里奥利共振阻止了对 R 分支跃迁的类似分析,该共振几乎完全将 R 分支跃迁的强度转移到 P 分支。弱线混合系数通过实验检索,并使用指数功率间隙标度法建模。使用满足所有基本关系的对称松弛矩阵,使用能量校正突然类型方法执行另一种建模。介绍和讨论了实验和计算参数与文献中可用结果的比较。
