Scientific paper

Copernicus observations are presently used to analyze the H2 level population of the J = 5, 6, and 7 rotational levels; this distribution is noted to be compatible with an H2 rotational excitation mechanism and incompatible with UV pumping. If H2 formation on grains is the source of the observed H2 level population distribution, the newly-created H2 molecules will be rotationally hot. Chemical models for diffuse clouds are strongly influenced by the assumption that H2 formation, rather than UV pumping, is responsible for H2 excitation.
