THE FULL COMPLEMENT OF GREENHOUSE GASES


This is a diagram of all the vibrational modes ('absorption bands') of the Earth's atmospheric gases; in the near-infrared range of the electromagnetic spectrum. Gases are detected by thermoelectric thermopile or bolometer detectors (below), 'what is incorrectly termed 'IR spectroscopy'; and by thermoelectric's complement, Raman (Laser Lidar) spectroscopy (above).

Notice that O2 and N2 (some 99% of the dry atmosphere) are only detected using Raman spectroscopy. This is due to their one (and only) vibrational mode being non-thermoelectric: they both have only symmetric vibrational modes, with no electric dipole moments to generate an electric charge by the thermopile and so are not transduced and thus detected. Notice the other greenhouse gases, CO2, CH4, and O3, with symmetric modes, also figured by Raman.

 N2 and O2 have been wrongfully assumed to be non-' greenhouse gases,' and this needs to be reviewed.

The so-called greenhouse gases have been wrongly interpreted. They are really thermo-transductive gases, only detected by thermoelectric transducers (thermopiles, bolometers, and the like).
