Notes. (a) The frequency corresponds to the F = 1/2–3/2 transition. (b) The frequency corresponds to the F = 17/2–15/2 transition. (c) The frequency corresponds to the F = 15/2–13/2 and F = 13/2–11/2 transitions. (d)The K = 9 transition at 348.911 GHz is likely to be detected, although it is blended with a CH3 OCHO line. (?) The “?” mark indicates uncertain line identification due to blending.
