Abstract

In the field of IR and Raman Spectroscopy there are several companies that commercialize the equipment and programs
for its manipulation. One of them, Bruker (Germany), markets the OPUS (OPtical User Software) program package that
SEARCH-1 brings with it with very valuable functions for the creation and expansion of spectral libraries.
Mattson-Unicam (UK) offers the WinFirst software package which has similar features to the above. For the creation of the Spectrum Libraries, the grouping of substances based on their characteristics or
applications can be taken into account. In this way, libraries of drugs, inorganic substances, solvents, among
others, can be found, which allows searches and comparisons to be carried out more efficiently. The structuring of a large number of spectra in libraries facilitates the search functions (with various work
algorithms) through the use of pattern recognition techniques, which determine common signals between the sample
and the stored spectra.
