Intramolecular hydrogen bonding (IHB) of 1-amino-3-imino-prop-1-ene (AIP), as the simplest

resonance-assisted hydrogen bond system in symmetric N–H· · ·N class, and its halo derivatives (F, Cl, and

Br) have ...

Abstract: Molecular structure and vibrational spectra of acetone, acetone-d3, and acetone-d6 were investigated by means of ab initio and density functional theory (DFT) calculations. The harmonic and anharmonic vibrational ...
