I've just posted the question Which spacecraft can see plants "glow" during photosynthesis during the day, and what wavelength does it use? in a different SE site. I can't remember the details of which spacecraft this was or how exactly it worked.
My question here is simply about light produced by vegetation during photosynthesis. In this question I've shown a hodgepodge of absorption or sensitivity spectra of photosynthesis, but what I'm looking for is an emission spectrum and some details about where in the process this light is produced.
The Wikipedia article Chlorophyll_fluorescence covers the topic in general and mentions 735nm but I'd like to be able to see a fairly accurate spectrum in order to compare it against absorption lines in the Sun's spectrum.
