We used AT Mopra telescope to map selected regions towards the supernova remnant (SNR) G347.3--0.5, one the best candidate for proving that SNRs do accelerate Galactic cosmic ray nuclei. The previous NANTEN observations found broad CO lines towards one region of the SNR, which were interpreted as a sign of SNR-molecular cloud interaction. However, a proto-stellar driven molecular outflow has been recently identified in the cloud, and is most likely responsible for the broad molecular lines. Furthermore, the emission from the molecular cloud does not show very good spatial correlation with the SNR's TeV emission, which is expected if TeV emission originates from cosmic ray protons. Our new observations with Mopra telescope provide improved spatial resolution, which allows us to re-examine which molecular clouds are associated with this SNR.
