If/, 137 (1970)] described a computer program that aided in the identification of organic compounds. The program compared experimental results obtained in an organic qualitative analysis laboratory with the corresponding data for each entry in the file and reported which entries in the file matched th< laboratory data. Unfortunately, the described program, which was written in IITRAN, was not very flexible. Also, the data file associated with the program was rather small (51 entries). As £ result, the usefulness of the system proved to be limited.
