Model for molecular absorption spectroscopy in the 1-100 Torr range in the presence of vibrational depletion - Applied to ${\text{CH}}_4$ in ${\text{N}}_2$ and dry air

Thomas Hausmaninger, Weiguang Ma, Ove Axner

When molecules whose collision induced vibrational decay rates are small are probed by molecular absorption spectroscopic (MAS) techniques the absorption signal can, under certain…
