The solid obtained after purification was characterized through typical bands of the ligand in the infrared region, as νCH stretching between 3000 and 2900 cm−1 and νCN stretching between 1500 and 1400 cm−1, presented in Fig. 2 for the IR and Raman spectra. Ab initio optimization of...
The infrared spectrum of SCF2 was recorded in the 1000–1400 cm−1 region with a resolution of 2.5 × 10−3 cm−1. The rotationally resolved ν1 and ν4 band systems were studied for the first time, and altogether 11 500 transitions were assigned. Both fundamentals are involved in ...
4 一、红外光谱的基本概念 3.红外光区的划分 根据实验技术和应用的不同，将红外光区分成三个区:近红外区、中红外区、远红外区。其中中红外区是研究和应用最多的区域，一般说的红外光谱就是指中红外区的红外光谱.■红外光区的划分如下表：区域名称 波长(µm)波数(cm-1)能级跃迁类型 近红外区 泛频区 ...
的红外光照射下，在波数为4000-400cm-1的红外光照射下，样品分子吸收红外光会发生振动能级跃迁，外光会发生振动能级跃迁，所测得的吸收光谱称为红外吸收光谱图以波数波数为横谱(Infraredspectrum)，简称红外光谱(IR)。谱图以波数为横，简称红外光谱坐标，透光度为纵坐标来表示为纵坐标来表示：坐标，以透光度为纵...
The infrared absorption spectrum of ICN has been recorded in the region 200-5000cm ~(-1) with a Bruker 120HR interferometer, and several tenthousands of lines have been measured with a precision between 0.0001 and 0.001cm ~(-1). Most of these lines have been assigned. These new data ...
