https://hitran.org/ : mostly infrared data, little optical and almost no UV, the large wavenumber, short wavelength spectrum where Rayleigh scattering, ionization, and photodissociation are significant. At very low densities, collisions will be far less common than photon interactions, so Beers-Lambert broadening probably won't be important. |

Computing MKS Cross Section
ω = 2 π c / λ
σ(m²) = ω⁴ α(F-m²)² /( 12 π ε₀² c⁴ )
- = ω⁴ 16e-12 π² ε₀² α(cm³)² / ( 12 π ε₀² c⁴ )
- = ω⁴ 4e-12 π α(cm³)² / ( 3 c⁴ )
- = 64e-12 π⁵ α(cm³)² / ( 3 λ⁴ )
- = 64e24 π⁵ α(cm³)² / ( 3 λ(nm)⁴ )
Define β = 64e24 π⁵ α(cm³)² / 3 = 6.52842e27 α(cm³)²

HITRAN
https://hitran.org/ : mostly infrared data, little optical and almost no UV, the large wavenumber, short wavelength spectrum where Rayleigh scattering, ionization, and photodissociation are significant. At very low densities, collisions will be far less common than photon interactions, so Beers-Lambert broadening probably won't be important.
