A. J. Apponi, T. C. Pesch and L. M. Ziurys, Steward Observatory, University of Arizona; and P. Wehinger and S. Wyckoff, Arizona State University, report the first detection of methyl cyanide in this comet: "On Mar. 20 the K = 0, 1, 2, 3 and 6 components of the J=8-7 transition of CH3CN near 147.1 GHz were observed using the NRAO 12-m telescope, with main beam brightness temperatures of 0.083, 0.059, 0.060, 0.081 and 0.053 K, respectively. Integrated intensities for the two strongest K components, K = 0 and K = 3, were 0.18 and 0.13 K km/s. In a search for vinyl cyanide (H2CCHCN) at 151.9 GHz and ethyl cyanide (H3CCH2CN) at 152.3 GHz, no emission was detected to limits of 0.03 K peak-to-peak of main beam brightness temperature."
