| Spectroscopists are often faced with the problem of identifying an unknown compound from a measured spectrum, defining what impurities are found in a sample, and verifying sample integrity. All of these applications can be solved by performing a spectral search.
In the past, spectral searching was done using deresolved or low resolution spectra. However, the availability of more affordable disk storage space and the introduction of faster computers combine to make searching higher resolution spectral libraries a much more viable and attractive option.
In addition to standard deresolved spectral data bases that contain spectra at 16 cm-1 resolution with data points every 8 cm-1 and 8-bit ordinate precision, Thermo also offers high resolution, 4 cm-1 spectral libraries with data points every 2 cm-1 and 16-bit ordinate precision. Searching with the high resolution, 4 cm-1 library vs. the standard deresolved, 16 cm-1 library results in improved spectral matches, enhanced spectral subtraction results, and overall better search results.
