Specific Corrections and Reanalysis of the Data:

The frequency for the italic v2 = 1, J = 2-1, F = 7/2-5/2 transition of 35Cl12C14N given by Townes et al. [48002] should read 23 938.6 MHz and not 23 928.6 MHz. In table IV of reference [51003] the column headings should be reversed for the observed transitions. In table IX of reference [56005] the J = 18-17 transitions for 37ClCN are not consistent with the other observations. These are not included in the present work. The Cl-C stretching vibration labeled italic v3 here rather than italic v1 as given in the literature.
