Scientific paper

We present new molecular spectral line and (sub)millimetre continuum observations of the IRAS2 region of NGC1333. Our data locates the (sub)millimetre counterpart of the IRAS source. This source is located at the centre of symmetry of two bipolar molecular outflows. The older 'fossil' outflow extends approximately north-south while a younger, highly collimated, jet-like east-west outflow terminates in a well-defined molecular bow shock. Multi-transition methanol line data suggest that the molecular bow shock is very cold and that shock interactions have greatly enhanced the methanol abundance. This source provides a striking example of a molecular counterpart to the frequently observed optical Herbig-Haro type bow shock structures and provides a valuable specimen for detailed shock chemistry studies.
