Catalog Service: Spectroscopy and ISM detection of formamide
Description
Formamide is the simplest bearer of peptide bond detected in the interstellar medium (ISM). There still exists a lack of laboratory data on its rotational spectrum in THz domain. We measured the rotational spectrum of formamide in the frequency range 400-950GHz. The ground and the first excited vibrational state of the normal species as well as the ground state of ^13^C isotopic species were analysed. The results obtained represent an extension by a factor of two in frequency range com- pared to previous studies. Among all transitions frequencies in the dataset about 45% are new measurements. A reliable set of rotational constants allows accurate predictions of transition frequencies in THz domain. Based on the spectroscopic results the v12=1 excited vibrational state of formamide was detected in the IRAM 30m line survey of Orion KL for the first time in the ISM.
