In numerous astrophysical cases molecular cooling and heating influence dynamical evolution of the medium. The existence of a significant abundance of molecules can be crucial on the dynamical evolution of collapsing objects. Because the cloud temperature increases with contraction, a cooling mechanism can be important for the structure formation, by lowering pressure opposing gravity, i.e. by allowing continued collapse of Jeans unsta","authors_text":"D.
