Abstract
New spectral parameters (line positions and intensities) have been generated for the ν6 band of HCOOH, which agree well with 0.002 cm−1 resolution infrared laboratory spectra. The line positions were derived from previously published spectroscopic constants [Bumgarner et al., 1988]. New relative intensities were derived from the analysis of A type and B type transitions. The new line parameters allow improved quantitative analysis of atmospheric spectra from the 1105 cm−1 Q branch, provided that the previously neglected HDO strong tropospheric absorption in this region is taken into account.
