Special Issue Information

Dear Colleagues,

It is our great pleasure to invite you to submit an article for a high-profile Special Issue of Molecules on the theme “Molecular Spectroscopy–Atomistic Simulation Crosstalk in the Study of Intermolecular Interactions. Intermolecular interactions are key to almost all events that involve molecules and how they interact with each other or their surroundings. They are present in many examples, such as reaction mechanisms or in supramolecular chemistry. The study of such interactions is unravelling the many secrets of those domains.

The study of intermolecular interactions is conducted by making use of a powerful toolkit involving spectroscopy and atomistic simulations that allow understanding those phenomena.

Different spectroscopic techniques can take the lead toward capturing a more broad picture of molecular systems in terms of physicochemical properties and dynamics in different environments as well as structural features. The computational approach has often found support with respect to experimental spectroscopy. In fact, the increasing complexity of these experimental techniques makes it progressively more difficult to decipher spectroscopic results without the help of computational chemistry. To this day, the paths of spectroscopy and computational chemistry remain intertwined in an iterative process, where one both challenges and reinforces the other’s growth.

The development of the computational tools currently available to support spectroscopic analysis is remarkable (from static to dynamic simulations, from single-molecule to periodic systems, from molecular mechanics to ab initio approaches), and examples of this fruitful collaboration are widespread and truly multidisciplinary.

The Special Issue “Molecular Spectroscopy–Atomistic Simulation Crosstalk in the Study of Intermolecular Interactions” will bring together contributions from all aspects of this synergistic collaboration between computational spectroscopy and intermolecular interactions. Thus, it will provide readers the opportunity to easily obtain a bird’s-eye view of the state of the art in the field while offering authors the chance to showcase their research work on a high-visibility platform.

Manuscripts describing original research, perspectives, and reviews focusing on the combined computational and spectroscopic approach are all welcome in this Special Issue of Molecules.

In this work, the structural dynamics of the chloromethanes CCl4, CHCl3 and CH2Cl2 were evaluated through a computational spectroscopy approach by comparing experimental inelastic neutron scattering (INS) spectra with the corresponding simulated spectra obtained from periodic DFT calculations. The overall excellent agreement between experimental and calculated spectra allows a confident assignment of the vibrational features, including not only the molecular fundamental modes but also lattice and combination modes. In particular, an impressive overtone sequence for CHCl3 is fully described by the simulated INS spectrum. In the CCl4 spectrum, the splitting of the ν3 mode at ca. 765–790 cm−1 is discussed on the basis of the Fermi resonance vs. crystal splitting controversy. Full article
