摘要:已经开发了一个新的程序a-Tapax,用于获取从头计算数据并产生计算的INS谱。该程序使用苯从头计算数据进行了演示。利用振动的对称性将频率分配给观测到的峰值。A-TOPAX是第一个利用完全各向异性外部德拜-沃勒效应处理泛音(0-n;n>2)的程序。这些改进被证明改善了对数据的拟合。
Abstract.A new program, a-CLIMAX, has been developed to take ab initio data and produce a calculated INS spectrum. The program was demonstrated using benzene ab initio data. The symmetry character of the vibrations was used to assign the frequencies to observed peaks. a-CLIMAX is the first program of its kind to treat overtones (0-n; n>2) with fully anisotropic external Debye–Waller effects. These advances were shown to improve the fit to the data.
