Self-training, self-optimizing expert system for interpretation of the infrared spectra of environmental mixtures.

A program for the identification of the principal components of mixtures through interpretation of the infrared mixture spectrum (IntIRpret ) was developed. This program, which was developed as a preliminary screening tool for unknown organic mixtures, has five main subroutines: the interferogram processing and peak-selection subroutine (PUSHSUB), the automated knowledgeacquisition subroutine ( AUTOGEN ) , the system optimization subroutine (STO) , the interpretation subroutine (PAIRS), and fii processing subroutine to subtract spectral similarity (PAIRSPLUS) . Principal advantages of this system compared to earlier systems are speed, fIexibility and accuracy.
