What's the difference between IR absorbance and thermal conductivity? The absorbance is exactly that. The molecule absorbs the energy and is excited in the form of bond rotation, spin, bouncing around, etc. The more complicated the molecule the more energy it will absorb and at more wavelengths. This is one method analytical chemists might determine the composition of an unknown for example. Thermal conductivity is the measure of how much of this absorbed energy is given off as it collides with other gas atoms. Keep in mind the N2 and O2 that are dominant in the air also absorb IR and water vapor absorbs even more and typically 2.0 - 4.0%. Therefore 400ppm is nothing,
