Project Title
The Non-Coincidence Effect and Raman Spectroscopy
Abstract

Instrumentation for polarization-dependenct Raman spectroscopy experiments was set up. Raman scans of CCI4 were recorded and the depolarization ratios were compared to literature values. The non-coincidence value, a difference between isotropic and anisotropic peak placement, was recorded for three different compositions of the acetone/carbon tetrachloride binary liquid reference system. This data was taken over the region of 1680 to 1780 cm-1 looking at the C=O acetone vibration. Satisfactory qualitative agreement with literature data was obtained. Improvements in quantitative agreement are expected following the installation of a new monochromator. A sample housing intended for measuring the non-coincidence effect as a function of temperature was also designed.
