ALMA Detection of Interstellar Methoxymethanol (CH<sub>3</sub>OCH<sub>2</sub>OH),
Astrophys. J. 851 L46 (2017).
More than two dozen unblended or essentially unblended transitions were detected in several small recordings in Bands 6 and 7 through observations of the high-mass starforming region NGC 6334I-MM1. Assuming an excitation temperature of 200 K, its column density was found to be lower than that of methanol by a factor slightly larger than 30.
