乙炔(2v5-v5)、(v4+v5)-v4和(2v4-v5)I-2v4Q—支高分辨二极管激光光谱
(2v5-v5)、(v4+v5)-v4 and (2v4-v5)I-2v4 Q branches of high resolution diode laser spectra of acetylene
摘要
用高分辨二极管激光光谱仪对乙炔v5区域的几个Q支作了研究.在725cm~(-1)附近观察到(2v4+v5)I-2v4的Q支.并对(2v5-v5)和(v4+v5)-v4的Q支进行了观察.观测到一些微扰现象.对观测到的谱线利用最小二乘法进行了拟合,得到了部分分子常数.
Abstract
This artical presents the high resolution study of several Q branches of acetylene in region of v5 band by means of a diode laser spectrometer. The Q branch of (2v4+ v5)I-2v4 band next to 725cm-1 has been observed for the first time. The (v4+v5) -v4 and 2v5-v5 Q branches have been investigated. Some effects of perturbation have been observed. The obtained lines have been least-squares fitted and molecular constants have been obtained.
