Abstract- When dealing with IR spectroscopy, the pre processing of spectral data is considered to be one of the most important parts of chemometrics modeling. Due to any uncontrollable physical variations may lead to an additive, multiplicative and wavelength-dependent scattering effects in the recorded spectra. Pre-processing techniques basically are required to remove these scattering effects from the spectra and subsequently improve further quantitative and qualitative analysis. popular pre-processing techniques are; baseline correction, smoothing of the spectra, normalization, scattering correction, and spectral derivatives. This paper begins with the theoretical and mathematical foundation of various pre-processing techniques used for IR spectroscopy. Then a qualitative analysis is performed by applying these techniques on the spectral data collected using various samples of ghee. The comparison of various pre-processing is obtained by modeling the data using Principle Component Analysis (PCA) and then the k means clustering algorithm.
