Abstract . A self-consistent model for the dynamical and chemical evolution of dense interstellar clouds is examined. The model includes the basic atomic and molecular constituents of dense clouds and the reactions in which they are involved. ... The results of one-dimensional modeling of the early stages of collapse of protostellar clouds of different masses under the action of ultraviolet radiation are presented. Astrophysical applications of the results obtained are discussed. ...
