Four consecutive HC/sub 5/N transitions J = 7--6, 8--7, 9--8, and 10--9 have been recorded for each of the three sources Sgr B2, TMC 1, and IRC +10216. The observed line brightness temperatures have been used to derive HC/sub 5/N rotational temperatures: 28 K for Sgr B2, 5.5 K for TMC-1, and 13 K for IRC +10216. These are consistent with temperatures previously estimated for these molecular clouds. The J = 55--54 transition of HC/sub 11/N was searched in TMC-1 but was not found.
