===== On Amidogen, NH2, in Extragalactic Sources =====

Amidogen was detected with ALMA within cycle 0 observations in the unnamed foreground galaxy at //z// ≈ 0.89 toward the blazar PKS 1830–211 by\\

The strongest //J// = 1.5 – 1.5 and the weaker 1.5 – 0.5 fine structure components of the 1<sub>10</sub> – 1<sub>01</sub> transition of //para//-amidogen at 462446.5 and around 461440 MHz were detected in absorption, the latter with partially resolved <sup>14</sup>N hyperfine splitting.
