Observations of Diffuse and Translucent Clouds
Published online by Cambridge University Press: 07 August 2017
Abstract
Observations of interstellar CN, CH, and CH+ in diffuse and translucent clouds obtained with a spectral resolution of more the 500,000 are reported. First results from a survey of CH and CH+ are discussed. The CH+ isotopic ratio has been determined to be 68±5 toward ζ Oph and a component of 12CH+ has been found with a velocity width of 15 km s−1. A review of the rotational excitation temperature of interstellar CN and its implications is given.
