Notes. (a)See table 1 for quantum number formatting. (b)Radial position of peaks were obtained from multiple-Gaussian fitting, except for the faint c-C3H2 transitions. (c)Rpeak refers to the peak of the integrated intensity profile, while the uncertainty is assumed to be a quarter of the beam major axis, as Gaussian fitting was not possible.
