Scientific paper

Searches for three transitions of pyrrole (C4H5N) give maximum column
density = 3-10 x 10 to the 13th per sq cm in Sgr B2. This limit is more
than 10 times lower than previous ring molecule limits, and is slightly
lower than column densities of known interstellar molecules with from
four to six heavy atoms.
