Authors: Cabezas, Carlos; Kawashima, Yoshiyuki; Bermudez, Celina; Usami, Tsuyoshi; Hirota, Eizi; Cernicharo, Jose Journal: SPECTROCHIMICA ACTA PART A-MOLECULAR AND BIOMOLECULAR SPECTROSCOPY Publication date: 2023/04/15 DOI: 10.1016/j.saa.2023.122353 Abstract: A peptide linkage -(C--O)NH- containing molecule, N-ethylformamide, was investigated by rotational spec-troscopy in order to determine the molecular constants of its highest-energy conformer, cis -ac. Its rotational spectrum [...]
