... There are two important types of light sources used in spectroscopy: polychromatic and monochromatic sources. The polychromatic sources span a wide range of frequencies. For instance, many commercial spectrometers use light sources which emit radiation similar to black-body radiation from hot materi ...

This process will not sustain itself unless there is a continuing supply of atoms in excited states. This is ensured by exciting electrons into metastable states – excited states t ...

... graininess of matter, or equivalently, the fact that one atom can only absorb one photon at a time. Two photons then interact with one another because the first photon modifies the atom’s state, and hence the atom’s response to the second photon. What, then, is the limit to the interaction of one ph ...
