Abstract

Herein we present a laboratory rotational study of glycolamide (OHCH$_{2}$CONH$_{2}$) and an astronomical search for this molecule, a glycine isomer, and also one of the simplest peptide molecules that could reasonably be observed in the interstellar medium (ISM). Using a battery of state of the art rotational spectroscopic techniques in the frequency and time domain, \footnote{L. Kolesniková, E. R. Alonso, S. Mata, and J. L. Alonso, APJS, 229 (2017), 26-34 and references therein.} around 1500 transitions have been newly assigned. Based on the reliable frequency predictions, we report an accompanying radioastronomical search for glycolamide in the well known high-mass star forming region Sgr B2(N) using the ALMA imaging spectral line survey ReMoCA. \footnote{A. Belloche, R. T. Garrod, H. S. P. Müller, K. M. Menten, I. Medvedev, J. Thomas, Z. Kisiel, A\&A, 628 (2019), A10.} Glycolamide was not detected in this source, and we report corresponding upper limits to the column density, showing that glycolamide is at least around 6 times less abundant than acetamide.\footnote{M.
