The Composition of Interstellar Molecular Clouds
Space Science Reviews, 1999We consider four aspects of interstellar chemistry for comparison with comets: molecular abundances in general, relative abundances of isomers (specifically, HCN and HNC), ortho/para ratios for molecules, and isotopic fractionation, particularly for the ratio hydrogen/deuterium.

Magnetic Fields in Molecular Clouds
Annual Review of Astronomy and Astrophysics, 2007This review examines observations of magnetic fields in molecular clouds and what those observations tell us about the theory of molecular cloud evolution and star formation. First, the review briefly summarizes classes of theoretical models of molecular clouds and specific predictions of the models that can be tested by observation.

Theoretical models of star formation from the collapse of molecular cloud cores have been evolving in complexity for many years. This work describes the evolution of models from the nonrotating, nonmagnetized singular isothermal sphere to rotating, magnetized singular isothermal toroids. Four members of the same family are studied–the four combinations

Of specific interest for stellar formation are regions where matter in the ISM appears most dense and in the form of clouds. Although there is no particular definition of the term cloud, it describes regions with a density larger than about 10 to 30 atoms per cm3. There are diffuse clouds, which do not reach these densities, and self-gravitating clouds

This chapter discusses the Taurus molecular cloud. Sources are extracted from the SCUBA-2 850-\(\upmu \)m data, Herschel 250-\(\upmu \)m data, and Herschel 250-\(\upmu \)m data filtered to match the spatial scales detectable with SCUBA-2.
