Scientific paper

We present high resolution observations of the intensity and velocity fields of the embedded cores NGC 1333 IRAS2, NGC 1333 IRAS4, and L1448N as mapped by the J = 1 --> 0 rotational transitions of C18O, H13CO+, and N2H+. These lines are optically thin and trace the core kinematics over a range of critical densities. We find that thermal broadening is insufficient to explain the emission line widths. Moreover, the behavior of the line widths as a function of spatial resolution is consistent with the turbulent MHD model clouds created by Ostriker, Stone, and Gammie.
