First Glycine Isomer Detected in the Interstellar Medium: Glycolamide (NH2C(O)CH2OH)
Astrophys. J. Lett. 953, Art. No. L20 (2023).
The molecule 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 transitions cover 31 to 98 GHz with 1 ≤ J ≤ 7 and Ka ≤ 5. Some lines are unblended, slightly blended, or the peak of the line is at most slightly blended. Some further lines are blended more substantially. The glycolaldehyde/glycolamide ratio is ∼15, while the ethanol/ethanolamine ratio is ∼40.
