Notes. Transitions are assigned with the usual rotational quantum numbers of the upper and lower levels. For transitions within the H-out-of-plane configurations, the + or − signs identify tunneling sublevels. Only the 40 lowest frequency transitions appear in this table.
Obtained in the hyperfine structure analysis of Sect. 3.4.
The measurement set as defined in Sect. 2 is given.
