✦ Synopsis

Ahstmct

A method of Fourier deconvolution of infrared OR) spectra using a reference band is developed. The deeonvolution function is given by an expression of the type exp[ -(Ax)P], where A is the deeonvolution half-width and the parameter p is determined by the experimental reference band shape. The specific experimental conditions are additionally taken into account by the ratio R(x), in which deconvolution function is modified with the normalized experimental interferogram of the reference spectrum. The proposed procedure allows overdeconvolution to be controlled. The reference band is selected either from the IR spectrum being studied or from the spectrum of another compound. Two principal restrictions are included: the reference band should be symmetric and must be recorded under the same conditions as the IR spectrum, subject to the deeonvolution.
