Abstract

We have measured the Fourier transform spectrum of natural OCS from 3700 to 4800 cm-1 with a near Doppler resolution and a line-position accuracy between 4 and 8 x 10(-5) cm-1. For the normal isotopic species, 37 vibrational transitions have been analyzed for both frequencies and intensities. We also report 15 bands of OC34S, eight bands of O13CS, nine bands of OC33S, and two bands of 18OCS. Important effective Herman-Wallis terms are explained on the basis of eigenvectors. A comparison of different line-pointing programs is also presented. Copyright 1998 Academic Press.

摘要

我们以近多普勒分辨率和4至8×10⁻⁵厘米⁻¹之间的谱线位置精度，测量了3700至4800厘米⁻¹范围内天然氧硫化碳（OCS）的傅里叶变换光谱。对于正常同位素种类，已对37个振动跃迁的频率和强度进行了分析。我们还报告了OC³⁴S的15条谱带、O¹³CS的8条谱带、OC³³S的9条谱带以及¹⁸OCS的2条谱带。基于本征向量解释了重要的有效赫尔曼 - 沃利斯项。还给出了不同谱线指向程序的比较。版权所有1998年学术出版社。
