The Excitation of N2H+ in Interstellar Molecular Clouds. II. Observations

We present observations of the J=1-0, 2-1, and 3-2 rotational transitions of N2H+ and N2D+ toward a sample of prototypical dark clouds. The data have been interpreted using nonlocal radiative transfer models. For all sources previously studied through millimeter-continuum observations, we find a goo...
