An expert system for the interpretation of infrared spectra EXPIRS was created. The main features of EXPIRS are: hierarchical organization of the characteristic groups, realized by frames; registration of the multiple use of spectral bands; taking into account the solvent absorption and the chemical

✦ Synopsis
A system for the automated elucidation of chemical structures by the interpretation of infrared spectra is described. "Rules" for the finding of substructure features in an unknown spectrum are obtained by a pattern recognition procedure. A structure generation algorithm links particular substructures, called "superatoms", together. Fuzzy set operators are used to consider inaccuracies in peak positions and intensities.

A knowledge base is proposed that adopts a set of rules that express the laws of spectra interpretation and the experience of special field experts in order to imitate the reasoning process of the human brain in relation to the group-frequency correlation of organophosphorus compounds.

An improved version of the expert system for infrared spectra interpretation, EXPIRS, was created. A new algorhhm for the generation of alternative sets of substructures was proposed on the basis of the PROLOG inference engine, that implements simultaneously the control of the number of utilizations
