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
|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 MHzMHz|
The centrifugal distortion results given are identical to those reported by Kirchhoff , 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.
