分子光谱学试题
一. 翻译（10 分）
1) normal modes of vibration; 2) Raman effect; 3) depolarization ratio; 4) SERS;
5) interferometers; 6) liquid cells; 7) attenuated total reflection; 8) group frequencies;
9) inductive effects; 10) difference spectra
二. (10 分)
1. Liquid films provide a quick method of examining liquid samples (A drop of liquid is
sandwiched between two infrared plates, which are then mounted in a cell holder.).
The method of liquid films is normally not used for volatile (with a boiling point less than
100o
C) liquids, why would this be necessary?
2.
上图中哪种振动是红外活性的? Which one of the vibrations is “infrared-inactive”?
三. （10 分）
1. Given that a molecule contains oxygen, how would an infrared spectrum of such a
molecule be used to find out whether the compound was a carboxylic acid (羧酸), a phenol
(酚), an alcohol or an ether(醚)?
2. 固态对位羟基苯乙酮的 O—H 伸缩振动出现在 3130 cm-1
，而其氯仿稀溶液（0.002M）
相应的红外吸收出现在 3600 cm-1
, 请解释两者产生差异的原因。
