M. ; Saykally, R. J. ; Plambeck, R. L. ; Erickson, N. R. Abstract We report the detection of five hyperfine components of the N = 3-2 transition of CCH in Orion A. From an analysis of this data combined with N = 1-0 data from previous observations, the rotational constants (B0 and D0) were determined, and the values of the fine structure (γ) and hyperfine constants (b, c) were improved. We predict the frequencies of additional rotational transitions of CCH up to N = 5-4. A rotational temperature and column density are estimated on the basis of the 3-2 data.
