Specific Corrections and Reanalysis of the Data:

Three transitions fit poorly and were excluded from the final analysis. Their calculated frequencies are shown below along with Δν which is νobs-νcal:

MHz
  11,0-10,1   42 324.390(14) MHz   Δν=0.400 MHz
152,13-161,16   20 474.989(22) MHz   Δν=0.229 MHz
154,12-163,13   20 649.868(19) MHz   Δν=0.218 MHz

The centrifugal distortion results given are identical to those reported by Kirchhoff [72031], however, the molecular constants are quoted with more significant figures. An improved analysis of the nuclear quadrupole interaction of 14N was obtained from a fit to 33 hyperfine components with a standard deviation of 0.047 MHz.
