Webb1 jan. 2024 · Introduction. Over the last fifty years, the HITRAN molecular spectroscopic database has provided scientists and engineers with the necessary data to predict and … When one works with the database, the Voigt line shape is usually assumed, which is a convolution of a Gaussian (Doppler-broadened) profile, fG(ν), and Lorentzian (pressure-broadened) profile, fL(ν). The half-width at half-maximum (HWHM) of the Doppler-broadened component is given … Visa mer To calculate the intensity at temperatures different from the HITRAN reference temperature of 296 K, one uses the following expression, which is derived from Eq. (1):Sij(T)=Sij(Tref)Q(Tref)Q(T)exp(−c2E″/T)exp(−c2E″/Tref)[1−exp(−c2νij/T)][1−exp(−c2νij/Tref)]… The pressure shift, δ, of the transition wavenumber leads to a shifted position ν∗ij given byν∗ij=νij+δ(pref)p.The pressure shift should also include a temperature dependence, but that … Visa mer In the atmosphere, a spectral line is broadened about the transition wavenumber νij, the spread being represented by the … Visa mer
