temperature compensation of novel ndir co2 gas sensor

Infrared Sensor Application Note 1 A Background to Gas ...

raises the gas temperature. The resonant frequencies (wavelengths) depend on the number and masses of atoms in the molecules as well as the number and strengths of the various chemical bonds. If the chemical structure of the molecules is complex, then there will be a whole range of resonant vibrations. This is often presented graphically as a series of absorption peaks plotted against ...
