We report an analytic result about the influence of the apparatus on the intensity ratio of the Raman peaks. This ratio of the Raman peak with the larger linewidth to the one with the smaller linewidth will increase with the increasing width of the instrument response function and the linewidth of the incident laser. For the applications of the empirical equations based on the intensity ratio of Raman peaks, the spectral resolution of the instrument should be indicated, and the fitting associated with a measured instrument response function is recommended.
