Lighting theory infrared radiation

The fact that the molecules are adsorbed on a solid surface giv rise to a number of new effects compared to the gas phase situation. The experimental situation consists of a monolayer of molecules adsorbed on a metal surface, on which we shine infrared radiation and then detect the reflected light. The macroscopic theory for the electromagnetic response of such a system is reproduce in the previous reviews. A more microscopic treatment has been given by Persson, showing that the integrated infrared absorptance for p-polarized light is given by ... 

The classical theory of electromagnetic radiation, attributed primarily to James Clerk Maxwell, describes radio waves, microwaves, infrared and visible and ultraviolet light, x-rays, and y-rays all as combinations of oscillating... 

In this section, we shall discuss the free ion yield produced by low LET radiation and make use of the Onsager theory of escape in order to rationalize the observed values. The free ion yield depends on the temperature of the liquid, on external hydrostatic pressure, on the externally applied electric field strength, and on the molecular structure of the molecules comprising the liquid. In some liquids, where electron trapping is involved in the transport, the yield can be influenced by simultaneous illumination with infrared light (see Section 3.8.3). Free ion yields produced by low LET radiation have been determined for many liquids. The discussion of all the details would exceed the frame of this book. The interested reader is referred to the reviews by Hummel and Schmidt (1974) or Freeman (1987).
