Abstract
A number of CH3OH lines toward the H-II region F in the NGC 6334 star-forming region have been observed in April 1987 with the 140-foot Green Bank telescope. Strong maser emission is found in the 2(1) to 3(0)E transition at 19.9 GHz and in the 9(2) to 10(1)A(+) transition at 23.1 GHz. The results suggest that the 12.1, 19.9, and 23.1 GHz methanol masers may be closely associated with compact H-II regions and OH masers, and that the 25 GHz masers may be associated with dense condensations in an earlier evolutionary state.
