Thermal emission of methanol and other molecules at millimeter wavelengths

Thermal emission of methanol and other molecules at millimeter wavelengths

The paper reports the results of a survey of Galactic star-forming regions in the methanol lines 8-1--70 E at 229.8 GHz, 3-2--4-1 E at 230.0 GHz, 00--1-1 E at 108.9 GHz, and a series of J 1--J 0 E lines near 165 GHz. In addition to the methanol lines, lines of methyl cyanide (CH3CN), cyanoacetylene...

Description
Summary:The paper reports the results of a survey of Galactic star-forming regions in the methanol lines 8-1--70 E at 229.8 GHz, 3-2--4-1 E at 230.0 GHz, 00--1-1 E at 108.9 GHz, and a series of J 1--J 0 E lines near 165 GHz. In addition to the methanol lines, lines of methyl cyanide (CH3CN), cyanoacetylene (HC3N), methyl formate (HCOOCH3), and sulphur dioxide (SO2) were detected. Analysis of the data indicates that the methanol emission arises in warm (30--50 K) gas.
