The PNNL-SERDP database was constructed by PNNL to generate the quantitative infrared spectra of gases associated with biomass burning; the reference data are to allow detection and quantification of such gases via infrared absorption spectroscopy. Candidates for the database were selected based on three criteria:
- known or suspected detection in biomass burnings events;
- strong infrared absorption features, especially in the 1300 – 700 cm-1 range
- the capability to be sampled using laboratory spectrometers, i.e. having sufficient vapor pressure so as to make the measurements.
