The every-day problem represented by the coexistence of several overlapped components in a narrow spectral range is treated.

The number of peaks, their analytical dependence and their symmetry can be defined by the user. The application of this software to some IR spectra of adsorbed species is presented and discussed in detail; particular attention is devoted to the description of the proper use of this complex deconvolution facility.

Abstract

The every-day problem represented by the coexistence of several overlapped components in a narrow spectral range is treated. A home-made deconvolution program (Asymgrad) has been developed in order to deal with this problem. Asymgrad is able to perfom spectral deconvolutions into up to 13 peaks. The number of peaks, their analytical dependence and their symmetry can be defined by the user. The application of this software to some IR spectra of adsorbed species is presented and discussed in detail; particular attention is devoted to the description of the proper use of this complex deconvolution facility. Examples are reported showing the way to escape some deconvolution traps.
