The user from Taiwan (IP: 2407::) uploaded a DOCX file containing three IR spectra. Swipe up to view the qualitative analysis of the third spectrum. The user also expressed intent to calculate sample thickness using interference peaks. Based on the spectra, the analysis was performed at wave numbers 3150 and 3290, yielding an interference peak difference (V₁ - V₂) of 140 cm-1 and ΔN = 1. By inputting the film's refractive index(n), the sample thickness (d) was determined.Here is the original spectrum of the sample extracted from the DOCX
