A SURVEY OF CYCLOPROPENYLIDENE (C3H2) IN GALACTIC SOURCES
Journal or Book Title
A survey of various Galactic sources reveals that C3H2 is one of the more abundant organic constituents of the dense interstellar medium. Detections of the 2(20)-2(11) para line at 21.6 GHz in many sources having strong 1(10)-1(01) emission are discussed. The 2(11)-2(02) line of the para species at 46.8 GHz has been detected in the dark clouds TMC-1 and L134N. The C3H2 emission is shown to be extended in the TMC-1, L134N, W51, and Orion clouds.
