Abstract
The rotational spectrum of the acetophenone–CO2 complex was investigated by pulsed jet-expansion Fourier transform microwave spectroscopy combined with ab initio calculations. In the supersonically cooled jet, only one isomer has been observed which is characterized by a dominant (CO2)C···O tetrel bond and a secondary (C-H)methyl∙∙∙O weak hydrogen bond. Johnson's non-covalent interaction, Bader's quantum theory of atoms in molecules and Symmetry-Adapted Perturbation Theory analyses have been applied to understand better the nature of non-covalent interactions in the acetophenone-CO2 complex.
