In relation to atmospheric spectroscopy and some other gaseous spectroscopy applications where organic molecules are present in the vapor, does anyone know of any papers or resources on pressure broadening due to hydrocarbons or other organic molecules in the vapor?

Broadening due to noble gases seems to have been well studied in various AMO sources,but it seems like slim pickings when you want to talk about larger molecules.

Specifically I'm looking at the line-broadening of alkali vapor absorption spectra due to the presence of short length alkenes in the vapor (Short means < 30 carbons)

Is the chemical nature of the partner gas B influencing line broadening for gas A? Is B not equivalent to a noble gas at the same partial pressure? My understanding is that broadening of lines of A originates in the partial component B being a collision "reservoir" which perturbs absorption by gas A. –  Lupercus Sep 13 '12 at 8:41
