The tables present the predicted the frequency of rotational transitions for the three 13C-isotopologues of ethyl cyanide, up to 600GHz and for J<60. The frequencies are calculated using a Watson's Hamiltonian in A-reduction in Ir representation.
The error on the frequency given in the tables is the standard deviation. To get an estimate of the "true" error it must be multiplied by a factor 3, for the strongest lines to 10, for the weakest lines. However, the general trend is that for the lines that are the most suitable for interstellar detection, i.e. the strongest lines having J value up to ~50 and a low Ka value, the error on the predicted frequencies is a few hundred kHz, suitable for line identification in the interstellar spectra. The error is larger for the weakest lines and increases as J and Ka become larger, i.e., as the frequency increases.
