Abstract: | A computer program, IRASSL, is described for processing infrared (IR) data. The program, based on symbolic logic, is used to formulate complex relationships between substructures and their characteristic wavenumber regions. The program yields sets of substructures inferred from a correlation table prepared from accumulated IR data. The procedure is applied as an ancillary to the automated structure elucidation system CHEMICS. The introduction of the substructural information provided by IRASSL into CHEMICS as restrictions in the elucidation process produces a significant decrease in the number of candidate structures. Some examples of the application are given. |
