The room temperature absorption spectrum of formaldehyde, H2CO, from 6547 to 6804 cm i1 (1527 to 1470 nm) is reported with a spectral resolution of 0.001 cm i1 . The spectrum was measured using cavity-enhanced absorption spectroscopy (CEAS) and absorption cross-sections were calculated after calibrating the system using known absorption lines of H2O and CO2. Several vibrational combination bands occur in this region and give rise to a congested spectrum with over 8000 lines observed. Pressure… Expand
