The rotation of molecular clouds (MC) during their collision with each other plays a decisive role in the formation of protostellar structures. The research carried out in this work makes it possible to improve the understanding of how the angular momentum of rotation is transferred at all stages and in different areas of colliding MC’s. Interest in the study of MC collisions and their influence on the formation of new stars has arisen for a long time. It should be noted that in most works, collision problems are investigated without taking rotation into account. This paper presents the results of direct and tangential collisions of two MC’s, whose rotation axes are perpendicular to the collision line. It is shown that the main contribution to the formation of a superdense substance that appears in the contact zone is made by the kinetic energy of the impact. Allowance for rotation (in one direction or in opposite directions) has a significant impact on the radial and azimuthal formation of filaments and clumps compared to collision studies without rotation.
