Our simulations account for the non-isothermal nature of the gas and include a simplified treatment of the time-dependent gas chemistry. We model the CO line emission in a post-processing step using a 3D radiative transfer code. We consider mean number densities n_0 = 30, 100, 300 cm^{-3} that span the range of values typical for MCs in the solar neighbourhood and investigate the slope \\alpha_{PCA} of the pseudo structure function computed by PCA for several components: the total densit","authors_text":"Christoph Federrath, Erik Bertram, Julia Roman-Duval, Rahul Shetty, Ralf S.
