| Abstract: | Three second-derivative spectra identification (DESPI) programs have been developed. The DESPI-1 program is used for the computerized recognition of the spectral components in known binary mixtures. The DESPI-2 and DESPI-3 programs are applied to the automatic identification of unknown binary mixtures. The performances of these computer-assisted procedures are evaluated and compared for nineteen single compounds (purines and pyrimidines) and twelve binary mixtures. |
