Parameters of warm molecular clouds from methyl acetylene observations Alakoz A.V., Kalenskii S.V., Promislov V.G., Johansson L.E.B., Winnberg A. <Astron. Zh. 79, 610 (2002)> =2002AZh....79..610A =2002ARep...46..551A
ADC_Keywords: Molecular clouds; Spectrophotometry ; Radio lines Abstract: The results of a survey of 63 galactic star-forming region in the 6k-5k and 5k-4k methyl acetylene lines at 102.5 and 85.5GHz are presented. Fourty-three sources were detected at 102.5GHz, and twenty-five at 85.5GHz File Summary:
