项目摘要

We have investigated IR-Vis Sum-Frequencey-Generation Circular Dichroism of the molecules on the substrate surface. This technique may provide 1 08 more efficiency than any other kinds of techniques to study the chirarity of molecules.We have reformed our old conventional ps-YAG laser and OPG/OPA system with LBO Crystal. We obtained IR laser beams by taking differential frequency of a fundamental YAG and the idler beam of OPA on a AgGaS2 crystal. We have inserted a quarter-wave plate into a visible beam to make left and right polarized light, and then mixed with the IR beam to obtain SFG-CD signal.The samples used in the experiment were ferro- and antiferro- electric liquid crystal molecules. We have successfully obtained SFG-CD signal for 1 0 molecular layers thick samples, but not for a single molecular layer sample. To overcome this difficulty we have changed the visible (2co) beam to UV.
我们研究了衬底表面分子的IR-Vis和频圆二色谱。我们用LBO晶体对传统的PS-YAG激光器和OPG/OPA系统进行了改造。我们在AgGaS_2晶体上分别取基频和OPA的闲置光束,得到红外激光光束。我们在可见光中插入四分之一波片,产生左右偏振光,然后与红外光束混合,获得SFG-CD信号。实验中使用的样品是铁电和反铁电液晶分子。我们成功地获得了10个分子层厚样品的SFG-CD信号,但没有获得单个分子层样品的SFG-CD信号。为了克服这一困难,我们将可见(2Co)光束改为紫外光。
