NIST 79. NIST Quantitative Infrared Database

Abstract
The NIST Quantitative Infrared Database currently consists of a collection of 21 absorption coefficient spectra of volatile organic compounds. These spectra were measured from primary gas standards prepared and verified at NIST. Spectra are provided in 5 resolutions from 2.00 cm-1 to 0.125 cm-1 using 5 apodization functions. The data file format conforms to the standard JCAMP-dx format and should be readable by commercially available analysis programs. Also included is an uncertainty estimate for the absorption coefficient data, which includes the estimated uncertainties associated with compound purity, primary standards, computation and instrumental performance.Included with the database are programs to allow viewing, printing and verification of the spectra. For users in the US and Canada verification is accomplished through digital signature of the spectra file; for international users it consists of 32-bit CRC. Verification guarantees that the data file has not been altered, and thus istraceable to NIST. A NIST certificate of traceability can be viewed and printed for each of the spectra.Citation
