UPPER LIMITS FOR THE ETHYL-CYANIDE ABUNDANCES IN TMC-1 AND L134N - CHEMICAL IMPLICATIONS
Journal or Book Title
ASTROPHYSICS AND SPACE SCIENCE
We have sought interstellar ethyl-cyanide via its 202–101 transition towards two cold, dark clouds and report upper limits of the total column densities of 3×1012cm–2 and 2×1012cm–2 for TMC-1 and L134N, respectively. We also observed the 202–101 transition of vinyl cyanide previously identified in TMC-1 by Matthews and Sears (1983b). The detection of vinyl cyanide and the non-detection of ethyl cyanide in TMC-1 are consistent with gas phase ion-molecule chemical models, and there is thus no necessity of invoking grain surface synthesis for vinyl cyanide in cold clouds.
