Mellqvist, A. Rosen Title: DOAS for flue gas monitoring-I. Temperature effects in the U.V./visible absorption spectra of NO, NO2, SO2 and NH3 Journal/Source: J. Quant. Spectros. Rad. Trans., 56 (2), 187-208, (1996); doi:10.1016/0022-4073(96)00042-8 Data: diagram Energy/Wavelength range: Resolution: Temperature: Temperature dependence: Pressure/Concentration: Phase: gas pH: Comments: The temperature dependence of the absolute and the differential absorption cross-sections for NO, SO2, NO2 and NH3 were studied by recordings of spectra in a heat-pipe cell.
