Abstract

Historically, infrared spectra libraries have been used mainly for qualitative analysis and functional group assignments with some limited use for quantitative analysis. The latter application mainly uses reference libraries for selecting an absorption band free from other interfering bands for quantitative methods development. The marrying of digital computers to infrared spectrometers has expanded the uses of reference libraries. In addition to the above applications, requirements now include computerized searches for reducing the task of unknown identification, rapid recall of reference spectra for viewing, and even digitized spectrum recall for spectral subtraction when a sample is not available for actually measuring the reference spectrum. All of these applications for spectral libraries cannot necessarily be achieved with the same data base, but for a library to be useful for qualitative analysis, it certainly needs to contain as large a number of reference compounds as it possibly can. In addition, the library user must be able to view the full reference spectra as rapidly as possible.
