Search of interstellar pyrrole: evidence that rings are less abundant than chains

· Astrophys. J.; (United States)
Searches for three transitions of pyrrole (C/sub 4/H/sub 5/N) give maximum column density N/sub max/=3-10 x 10/sup 13/cm/sup -2/ in Sgr B2. This limit is more than 10 times lower than previous ring molecule limits, and is slighly lower than column densities of known interstellar molecules with from four to six heavy atoms.
