Abstract: | We have studied the behavior of the inner motions of OH, H2CO, and CO molecular clouds. This study shows the existence of two main components of these clouds: the narrow one, associated to dense small clouds and a wide one representing the large diffuse clouds seen in neutral hydrogen, the large clouds are the vortex and intermediate state between turbulent and hydrodynamic motions in the Galaxy.For the dense clouds with sizesd<10 pc we have found a relationship ![sgr](/content/k5820486k7727422/xxlarge963.gif) d
0.38 consistent with the Kolmogorov law of turbulence; the densities and sizes of these clouds behave asn d
–1. This last relation for these molecular clouds is compared with theHII one. Also, we discuss the effects of the inner magnetic field in these clouds. |
