对氯硝基苯光谱低频晶格振动谱线展宽的原因
The Reasons of Line Broadening of Lattice Oscillations in Spectrum Small Frequencies of P-Chloronitrobenzene
摘要:
用极化法研究了293K下对氯硝基苯的晶格振荡。对氯硝基苯与对溴氯苯和对二溴苯的发光二极管光谱匹配表明,对氯硝基苯的显着谱线增宽不仅是由于对位取代苯分子的分布混乱造成的。这是必要的,也考虑和杂波在旋转位移的硝基基团有关的一个平面的分子。频谱的计算采用达因法.
英文摘要:
Raman spectroscopies are carried out by the Method polarizable examinations of the lattice oscillations of p-chloronitrobenzene at temperature 293 K. The led matching of spectrums of p-chloronitrobenzene with p-bromochlorobenzene and p-dibromobenzene has shown that the significant line broadening in p-chloronitrobenzene is caused not only clutter in allocation of molecules concerning parasubstitution benzol. It is necessary to consider also and clutter in rotational displacements of the nitro of group concerning a plane of a molecule. Calculations of frequency spectra were led on a method the Dyne.
