Refrigeration of the 18.3 GHz C_3H_2 Transition in Dark Clouds G1.6-0.25We have observed the 1_(10)-1_(01) (18.3 GHz) transition of orthocyclopropenylidene, C_(-3)H_(-2), at 24 positions in the unusual dense cloud G1.6- 0.025. Except for one position, the transition is refrigerated, a phenomenon which has not been seen in this transition before.
