2. Spectral properties of materials
2.1 Preamble
When an atom or molecule interacts with an incident electromagnetic wave of wavelength λ = 1/ν where ν is the wavenumber, quantum mechanics tells us that the atom or molecule absorbs the incident radiation by passing from an energy level E 1 , associated with state 1, to an energy level E 2 , associated with state 2, only if the tuning condition is satisfied :
Energy levels of the order of a few eV correspond to wavelengths...
