| HNSO was detected in the course of a molecular line survey of the Galactic Center molecular cloud G+0.693–0.027 employing the Yebes 40 m and IRAM 30 m radio telecopes. The //a//-type transitions cover 34 to 171 GHz with 1 ≤ //J// ≤ 10 and //K<sub>a</sub>// ≤ 2. Six lines were deemed to be unblended, and 12 more were only slightly blended. An excitation temperature of ~12 K was derived. \\ | HNSO was detected in the course of a molecular line survey of the Galactic Center molecular cloud G+0.693–0.027 employing the Yebes 40 m and IRAM 30 m radio telecopes. The //a//-type transitions cover 34 to 171 GHz with 1 ≤ //J// ≤ 10 and //K<sub>a</sub>// ≤ 2. Six lines were deemed to be unblended, and 12 more were only slightly blended. An excitation temperature of ~12 K was derived. The molecule is slightly more abundant than the somewhat related HNCS molecule. SO and SO<sub>2</sub> are more abundant by factors of ~38 and ~5, respectively, while NS is ~3.5 times more abundant. The higher energy isomer HSNO was not detected.\\ |
