有机分子晶格振动谱中空位的表现
Manifestation of Vacancies in a Spectrum of Organic Molecular Crystal Lattice Vibrations
摘要：
使用拉曼光谱的方法，并考虑在单晶中的空位的分配的不均匀性，它表明，具有小强度（由空位的存在所引起的）的线具有较大尺寸的样品中的主要强度比在较小尺寸的样品中。空位浓度增加时谱线强度的增加可以揭示哪些谱线与样品中空位的存在有关。对于对二氯苯，它是在70 cm^{-1}场中晶格振荡光谱中强度较小的谱线。
英文摘要：
Using a method Raman of spectroscopy and considering a non-uniformity of allocation of vacancies in a monocrystal, it is shown that lines with the small intensity (caused by presence of vacancies) have a major intensity in the sample of a larger size than in the sample of a smaller size. Increase of an intensity of lines at vacancy concentration increase can reveal which lines are related to presence of vacancies in the sample. For a p-dichlorobenzene, it is lines of a small intensity in a spectrum of the lattice oscillations in the field of 70 cm^{-1}.
