Specific Corrections and Reanalysis of the Data:

In the reanalysis of 35ClNO, two measured lines were excluded from the fit since they show significant deviations. The 109,2-99,1 transition reported in [66012] at 111 213.25 MHz is calculated 1.48 MHz higher in frequency with an uncertainty of 0.14 MHz and the 180,18-170,17 line reported in [66012] at 198 798.54 MHz is calculated 15.62 MHz lower in frequency with an uncertainty of 0.18 MHz. The error in the 41,3-40,4 transition frequency reported in [75010] has been corrected to read 83 635.88 MHz. Very poor agreement was obtained in the centrifugal distortion fit to the 20,2-10,1 transition and hyperfine splittings for 37ClNO. The strongest components, the unresolved pair F = 7/2-5/2 and F=5/2-3/2, are calculated 0.80 MHz higher than observed and the F = 3/2-3/2 transition is calculated 1.32 MHz higher than observed. The hyperfine analysis included the three components of the 10,1-00,0 transition and the three unblended components of the 21,211,1 and 21,111,0 transitions. The discrepancy could arise from ignoring the 14N hyperfine splitting, although this appears unlikely since these splittings were apparently unresolved.
