  • The last step is de-excitation and it dominates, so Sinha the boss bunny in the lab that did the experiment said that they had to really press on the first step to excite a lot of NO2* to see even a bit of OH.

  • Re-emission and collisional de-excitation play important roles in a the current CO2 level atmosphere and would continue to play important roles in an atmosphere with doubled CO2 levels not sure why you're so fixated with that or even a pure CO2 atmosphere.

  • The processes (absorption of light, collisional energy transfer and emission) can be separated because the average time that an isolated CO2 molecule takes before it emits a photon is much longer that the time for collisional de-excitation (~tens of microseconds at atmospheric pressure, less, higher in the atmosphere).

  • The reason for this is that collisional de-excitation is much faster

    Eli Rabett and RW Wood

  • The reason for this is that collisional de-excitation is much faster like a few orders of magnitudethan emission so essentially all of the CO2 which absorbs an IR photon, losses it in a few microseconds.

  • The de-excitation of these molecules produces scintillation light.

  • So it is not physically impossible to re-emit at the same frequency, it is indeed physically perfectly normal to do so, but in different conditions other mechanisms such as collisional de-excitation will interupt the re-emission at that same frequency.

  • The intensity of the light typically is modulated at acoustic frequencies, and the subsequent collisional de-excitation of the gas produces a sound wave.
