Search for Refrigerated Molecules

It is well known that some molecules, notably formaldehyde (H2CO) and methanol (CH3OH), are found in absorption in cold molecular clouds, and therefore must be cooled (refrigerated) to temperatures below the Cosmic background temperature. We suggest that a class of ring molecules may be found in similar physical conditions. Because these molecules are larger, their lowest energy transitions are at lower frequencies. We propose to test the hypothesis that other ring molecules may be found via a search for both emission and absorption features of their lowest energy transitions. The Taurus Molecular Cloud (TMC-1) is known to be a prime candidate for molecule discoveries and we propose sensitive searches for select molecular candidates at the three positions.
