Specific Corrections and Reanalysis of the Data:

One transition was not included in the P 6 centrifugal distortion analysis since it shows a large deviation from the calculated value. In particular, the 142,12-151,15 transition is calculated at 27 632.73(30) MHz but is reported 2.15 MHz higher in frequency. Several other transitions listed below show fairly large Δν(obs-calc):

Transition   Δν(obs-calc) MHz
182,16-173,15     0.486
122,10-171,13     0.481
  80,8-71,7   -0.449
  85,4-75,3     0.640
  73,5-63,4     0.696
  71,6-61,5     0.436
  75,3-65,2   -0.430
  50,5-41,4   -0.606

Based on the students t test, which ranged from 2 to 3 for these lines they could not be excluded but the measurement accuracy is questionable in these cases.
