SUMMARY

The discussion centers on the analysis of Raman spectra for Cyclohexane, specifically focusing on the 802 cm-1 and 2853 cm-1 peaks. Participants noted conflicting results regarding which peak should exhibit higher intensity, influenced by factors such as excitation laser wavelength and sample preparation. Cyclohexane is commonly used as a reference material for calibration in Raman spectroscopy, but variations in instrument response and calibration methods can lead to differing peak intensities across different spectrometers. The consensus indicates that both peaks can vary in intensity based on specific experimental conditions.

PREREQUISITES
  • Understanding of Raman spectroscopy principles
  • Familiarity with molecular vibrations and their corresponding Raman peaks
  • Knowledge of calibration techniques for spectrometers

I’ve reached the end of what I can tell you about Raman calibration standards. Maybe someone else here can better address your concerns.

I have understood it all already now. And I found out my wine purity raman analyzer software can take calibration spectra of light luminescent sources and do the internal response calibration for right intensity. Without all the stuff you shared. I couldn't have gotten the idea especially i'd be calibrating focus too. And I will order the luminescent reference material for it. Thanks a lot for all the help. Appreciate it so much! Here is a toast to the favorite century-old wine :)
