R-branch (J + 1 <- J) transitions for J = 0, 1 and Q-branch rotational transitions for the v(5) = 1 vibrational state have been measured by waveguide Fourier transform microwave spectroscopy in the range 8-26.5 GHz. The Q-branch transitions include 28 direct l-type doubling transitions (kl = +1, A(1)) - (kl = +1, A(2)) with J <= 62, and 108 direct l-type resonance transitions following the selection rule Delta k = Delta l = +/- 2 with J <= 60 and G = lk - l vertical bar <= 3. A process called "regional resonance" was observed in which a cluster of levels interacted strongly over a large range in J. Workplace J.
