The discussion focuses on extracting the instrumental broadening effect in Raman spectroscopy, particularly its impact on Full Width at Half Maximum (FWHM) measurements. The instrumental broadening can be quantified using the formula Δλ ≈ db/f, where d is the grating spacing, b is the slit width, and f is the focal length of the optics. Participants discuss how to determine the values for these parameters, emphasizing that a small instrumental broadening relative to the FWHM indicates accurate linewidth measurements. Additionally, the relationship between wavelength and Raman shift units is clarified, highlighting the importance of converting units appropriately for error analysis. Understanding these factors is crucial for optimizing Raman peak measurements and ensuring accurate spectral analysis.
