The observed rotational properties of dark clouds are shown to be consistent with the turbulent character of the interstellar medium. The turbulent flow is easily maintained by the shearing action of differential galactic rotation. The size distribution of molecular clouds inferred from observations is found to closely resemble a Kolmogorov turbulent spectrum. These findings suggest that the processes leading to the formation and evolution of such clouds may depend strongly on the properties and characteristics of interstellar turbulence.
