| Research Abstract |
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.
