ABSTRACT:

In this paper, IR spectroscopy which uses the Fourier transform is dealt with using Wavelet
Transform. Data from FTIR instrument is re-analysed using MATLAB programs prepared for this
purpose. Analysis of peaks of carbonyls, OH groups etc using such wavelet transform reconstruction
indicates additional remarks and a better elucidation of chemical structures. The principles, the
method are fully illustrated with typical chemicals.
