High-resolution (C-12)O and (C-13)O data on the carbon monoxide outflow and the properties of the molecular gas were examined around the FIR point source IRAS 04325-1419 in Lynds 1642. The estimated dynamical time scale of the CO outflow is about 40,000 yr. The force, F, and the stellar mass loss rate were found to be comparable with those derived from optical observations of T Tauri winds. It was found that the CO outflow around IRAS 04325-1419 is confined roughly within the boarder of a region of enhanced temperature with T(ex) = 14 to 16 K. It is suggested that this temperature enhancement results from a collision at the interface between the stellar wind and the ambient cloud.
