Abstract

This paper describes a new approach to the interpretation of spectra with ‘fuzzy sets’ and a fast search algorithm for spectrum libraries, using a combination of this theory and the inverse search method. The concepts are applied in a computer program named CIF (Compound identification with Inverted search and Fuzzy sets) which is used in the current application for the interpretation of X-ray powder diffraction signals. The methods are readily applicable to other kinds of spectra such as IR, UV, chromatrography etc.
