Abstract (from CDS):

The first astronomical measurements of the Jk=182-181, 192-191, and 202-201 E transitions of methanol (CH3OH) are presented. A rotational temperature Trot=170(13) K was determined for the Sgr B2N-LMH core by combining the data from the Jk=132-131 and 172-171 E transitions. The total column density of CH3OH is NT(CH3OH)=4.2(6)x1017 cm–2, and the fractional abundance of CH3OH is X(CH3OH)~4x10–8. The H59α recombination line and a new unidentified line were detected.
