Discovery of Thionylimide, HNSO, in Space: The first N-, S-, and O-bearing Interstellar Molecule
Astrophys. J. Lett. 965, Art. No. L26 (2024).
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 Ka ≤ 2. Six lines were deemed to be unblended, and 12 more were only slightly blended. An excitation temperature of ~12 K was derived.
