Abstract

High-resolution Fourier transform spectra of the D(2)(M)Se with M = 76, 77, 78, 80, and 82 in the regions of the first and second bending overtones 2nu(2) and 3nu(2) near 1480 and 2210 cm(-1), respectively, were recorded for the first time and assigned. On the basis of these experimental data, rotation-vibration energies were determined and fitted together with those of the (010) state reported earlier (W. Jerembeck, H. Bürger, J.-M. Flaud, and Ph. Arcas, J. Mol. Spectrosc. 197, 215-221 (1999)) by using the "Global Fit" procedure. The obtained set of 43 fitted parameters for these three vibrational states of the D(2)(80)Se species (altogether 86 fitted parameters for 12 states of five M species) reproduces the rotation-vibration energies of all studied states with accuracies close to experimental uncertainties.

摘要

首次记录并归属了M = 76、77、78、80和82的D₂(M)Se在分别靠近1480 cm⁻¹和2210 cm⁻¹的第一和第二弯曲泛音2ν₂和3ν₂区域的高分辨率傅里叶变换光谱。基于这些实验数据，利用“全局拟合”程序确定并拟合了转动-振动能量，同时拟合了先前报道的(010)态的转动-振动能量（W. 杰伦贝克、H. 比尔格、J.-M. 弗洛德和Ph. 阿尔卡斯，《分子光谱学杂志》197, 215 - 221 (1999)）。对于D₂(80)Se物种的这三个振动态获得的43个拟合参数集（五个M物种的12个态总共86个拟合参数）以接近实验不确定度的精度再现了所有研究态的转动-振动能量。版权所有2000年学术出版社。
