"Spectrum" is quite vague. What kind of spectra? Atomic emission, absorption, fluorescence, inelastic scattering? There are many things to consider in some of these techniques, such as the probability of several relaxation processes, intermolecular and intramolecular interactions...
I am trying to find a way to determine the rate and function that would describe how a theoretical vacuum (let's say a cubic centimeter) would repopulate with air if surrounded by ambient air at STP. Any suggestions? I am not very good with thermodynamic or kinetic theory.
