The quantum systems that interact with light waves in spectroscopic experiments have been treated in preceding chapters as if these systems were to be studied one at a time. In practice, however, one ordinarily deals with macroscopic samples of matter, each of which consists of very large numbers (≅ 1020) of microscopic chromophores. Statistical methods must be used in such cases to predict the behavior of the sample, and it is the purpose of this chapter to develop appropriate techniques.
