Abstract A study is presented of the behavior of the H2 infrared emission spectra that are produced in dense static photodissociation regions exposed to UV radiation which both heats and excites the H2 gas. The theory of H2 excitation by UV radiation and the construction of one-dimensional steady state models which are used to compute the H2 infrared spectra for a wide range of cloud conditions are discussed. The results of a number of illustrative model calculations are presented.
