Spectroscopy, 229 (1), 115-121, (2005); http://dx.doi.org/10.1016/j.jms.2004.08.019 Data: table, diagram Energy/Wavelength range: 6547 - 6804 cm-1 (1527-1470 nm) Resolution: 0.001 cm-1 Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: The room temperature absorption spectrum of formaldehyde, H2CO, from 6547 to 6804 cm-1 (1527–1470 nm) is reported with a spectral resolution of 0.001 cm-1. Pressure broadening coefficients in N2, O2, and H2CO are reported for an absorption line at 6780.871 cm-1, and in N2 for an absorption line at 6684.053 cm-1.
