TL;DR: By combining rotational spectroscopy in supersonic expansion with the capability of state-of-the-art quantum-chemical computations in accurately determining structural and energetic properties, the genuine nature of a sulfur-sulfur chalcogen bond between dimethyl sulfide and sulfur dioxide has been unveiled in a gas-jet environment free from collision, solvent and matrix perturbations.

TL;DR: In this article, the rotational spectra for three conformers of 3,3-difluoropentane have been measured using both a newly constructed narrow bandwidth chirped-pulse Fourier-transform microwave spectrometer and a Balle-Flygare resonant cavity Fourier transform (FFT) microwave spectrameter.

TL;DR: Quantum chemical calculations predict a strong bonding interaction and the strength of the H2-AgCl complex has been related to reported χ(aa) and Δ(J) values amongst a host of comparable species, including the AgCl monomer itself.

TL;DR: Rotational spectra of the normal isotopic species and three (13)C isotopologues of the 1:1 complex between vinyl fluoride and difluoromethane have been measured using 480 MHz bandwidth chirped-pulse Fourier-transform microwave spectroscopy in the 6.5-20 GHz region.

TL;DR: Tests indicate that for systems of this size, a uniform treatment of anharmonicity with systematically improved performance is not yet in sight, and discrepancies between experiment and theory for the isomer abundance are tentatively assigned to electronic structure deficiencies.
