Two methods can be used to obtain the inverse Fourier transform of the lineshape function: an analytical and a numerical method. The numerical method gives some errors which limit the degree of enhancement. The analytical method overcomes these difficulties but necessitates a mathematical development. The numerical method is the only way to obtain an inverse Fourier transform of an experimental spectrum, and some aliasing is introduced by the algorithm used. The infrared spectra of the carbonyl containing compounds are used to illustrate the effectiveness of the procedure described en_US dc.format.extent 92205 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title OPTIMIZATION OF THE FOURIER DECONVOLUTION TECHNIQUE TO ENHANCE INFRARED SPECTRA en_US dc.type article en_US
