Paper Abstract

Certain classes of organic charge-transfer salts demonstrate superconducting behavior at liquid helium temperatures. Single crystal x-ray diffraction and microreflectance FT-IR analysis have been performed on several conductin systems to deduce the nature of the crystalline structure which affect theg electrical conductivity. The infrared spectrum for a single crystal salt exhibits absorptions from the unsaturated organic salt as well as influences from the electronic transitions. There are strop correlations between particular absorption profiles and the single crystal conductivity. Routine examination of the long-term stability of the morphology as well as contamination of the single crystal may be studied.
