Abstract : The work described in this report was performed to determine the practicability of using existing infrared punched card data with a computer to improve storage and retrieval. Prior to this work, Wyandotte-ASTM Punched Cards were used with sorting machines for the purpose of matching infrared spectra in qualitative analysis and for correlating chemical structure and absorption band positions. The increasing amount of data (10,000 cards per year) made it desirable to find a faster soring system. The data from 51,734 Wyandotte-ASTM infrared punched cards were transferred to a magnetic tape and a computer program was written which allows for any logical sorting operation to be performed. The program was designed for as many as thirty-six separate ''problems'' or requests. The identification of organic and inorganic compounds by rapidly locating matching infrared spectra for direct comparison has been significantly improved with the development of this computer program. The significance of this program lies in the almost immediate identification of unknown compounds that are amenable to analysis by infrared spectroscopy provided that a spectrum of the compound is indexed by the Wyandotte-ASTM punched cards.
