The //J"// = 0, 1, and 2 transitions near 74.1, 148.2 and 222.3 GHz were detected in emission toward Sgr B2(OH) using the NRAO 12 m dish for the former, and the Texas MWO 4.9 m dish for the latter two transitions.

They detected the //J"// = 1 and 2 transition toward the dark cloud TMC-1 using the IRAM 30 m dish.
