Abstract

A simple analytic model is presented to predict the near-IR H2 fluorescent line intensities emitted by diffuse interstellar clouds with a Plummer density profile.

It is applicable to sightlines where (1) the column densities of H and H2 have been measured and (2) the peak gas density can be estimated from extinction maps or observations of C2 absorption.

;Comment: 5 pages, 1 figure.
