Raman Under LN₂: A Simple Approach to Low Temperature Raman Spectroscopy

Conventional low temperature Raman Spectroscopy techniques utilize expensive equipment to cool a sample to 77˚ K. In this work, a new technique for performing Raman Spectroscopy at liquid nitrogen temperatures is presented. This technique of taking data with the sample placed under liquid nitrogen provides a low cost alternative to conventional methods, and can be utilized by any lab with a Raman spectrometer without the purchase of additional equipment. Representative spectra for CCl₄, C₆₀, and Single Wall Carbon Nanotubes at room temperature and under liquid nitrogen are shown and compared as validation of the utility of this technique.
