The discussion focuses on the instrumental broadening effect in Raman spectroscopy, specifically how parameters like slit width, spectrometer length, and objective solid angle influence the Full Width at Half Maximum (FWHM) of Raman peaks. Key formulas include Δλ ≈ (d * b) / f for instrumental broadening, where d is the grating spacing, b is the slit width, and f is the focal length of the optics. The participants clarify that for a diffraction grating with 1800 lines/mm, N equals 1800, and they discuss the significance of minimizing instrumental broadening to ensure accurate FWHM measurements.
