HAS89 - The detection of the 4(-1)-3(0) E transition of methanol at 36.2 GHz toward hot H II regions

Short title: Haschick & Baan (1989)
Authors: Haschick, Aubrey D. Baan, Willem A.
Journal: Astrophysical Journal, Part 1 (ISSN 0004-637X), vol. 339, April 15, 1989, p. 949-955.

Abstract
Using Haystack Observatory at 36.169240 GHz, the 4(-1)-3(0) E transition of methanol toward 26 H II regions has been detected. The strong emission lines have narrow velocity components, thus exhibiting some of the characteristics of maser emission, as well as broader features which are assumed to be thermal in origin. The methanol emission preferably occurs in molecular clouds associated with hot H II regions and has not been detected in cold dark cloud regions or late-type stellar sources. The characteristics of the emission are discussed.
