Scientific paper

An investigation of the physical and chemical properties of nine interstellar dark clouds, L1407, L1551, L1544, L134N, L63, L1147, L1235, L1253, and L1257 are reported. Observations of a variety of atomic and molecular species have been obtained, and the clouds have been partially mapped in the near infrared. The observations have been compared with theoretical models of the line emission and absorption from interstellar clouds to derive many of the fundamental physical parameters. The temperatures, densities, masses, sizes, and abundances of atomic and molecular species in the clouds have been determined along with variations of the density and temperature as a function of radius.
