a Unpublished work of F.J. Lovas and R.D. Suenram, National Bureau of Standards, 1978. Also included in the analysis was the 11,1 - 20,2 at 7803.49(1) MHz reported privately by J. Muenter.

b Numbers in parentheses are measured uncertainties or standard deviation of calculated value and refer to the last digits given.

c This is the middle component of a resolved triplet. The other lines occur at 95 193.575(45) MHz and 95 194.220(45) MHz.
