INTRODUCTIONA number of computer search systems of infrared spectra data have been developed since 1967. The data used were mostly ASTM-WYANDOTT search cards based on Kuentzel’s digitizing method which codes a spectrum by YES or NO peak. Recently some search systems containing peak intensity information have been reported. However, because of the limitation of the number of data with intensity information, these systems are not in practical application yet. Although the binary YES/NO-data form does not reflect a spectrum exactly, the search program using such a kind of展开更多
