AbstractFor the first time, the OMC-2/3 region was mapped in C(2)H (1-0), HC(3)N (10-9) and HNC (1-0) lines. In general, the emissions from all the three molecular species reveal an extended filamentary structure. The distribution of C(2)H cores almost follows that of the 1300 mu m condensations, which might suggest that C(2)H is a good tracer to study the core structure of molecular clouds. The core masses traced by HNC are rather flat, ranging from 18.8 to 49.5 M(circle dot), while also presenting a large span for those from C(2)H, ranging from 6.4 to 36.0 M(circle dot). The line widths of both HNC and C(2)H look very similar, and both are wider than that of HC(3)N. The line widths of the three lines are all wider than those from dark clouds, implying that the former is more active than the latter, and has larger turbulence caused by winds and UV radiation from the surrounding massive stars
