This randomized trial examines vibrational spectra of formamide in ionized states, suggesting its role in biomolecule formation.

The aim is to investigate the vibrational spectra of the cationic and protonated forms of formamide.
Used leak-out spectroscopy and Ne-tagged infrared predissociation spectroscopy.
Conducted in a cryogenic 22-pole ion trap at the HFML-FELIX facility.
Spectra measured in the fingerprint region 650–1800 cm–1 and compared with anharmonic vibrational frequency calculations.
Detected spectral signatures of low-energy aminohydroxycarbene and higher-energy canonical cation for the formamide cation.
Protonated formamide observed solely as the stable O-protonated isomer.
Ne tagging subtly influenced vibrational signatures, revealing the precision of spectroscopic techniques.

Kaur et al. (2025) studied this question.
