Popis: A nearby (approx.100 pc) dark cloud complex in Taurus with embedded newly formed stars has been observed in CO J=1..-->..0 spectral lines in order to study the kinematics of the early phases of cloud collapse. Three of eight observed regions have localized multiple velocity components in CO, which are interpreted as indicating fragmentation and resultant orbital motion of parts of the clouds. Deviations from the conservation of angular momentum expected from simple spherical collapse are apparently observed. The observed fragmentation process is widespread in the complex and is probably a common phenomenon in cloud collapse.
