Scientific paper

The author has used new methods to study the turbulence in molecular clouds, i.e. Fourier tranforms of various line parameters from various CO isotopes. The studied cloud was found to be turbulent. That is, the spectral indexes of the power spectra are consistent with the Kolmogoroff law. It is found that the column density of a fluctuation increases with increasing size. It is also shown that the thermal variations are controlled by the dominant coolant 12CO.
