Ab Initio Multireference Quantum Chemical Investigations of Molecules: Chemical Bonding, Spectroscopy, and Beyond

Dear Colleagues,

Ab initio multireference methods are widely utilized in electronic structure theory. The progression of applying multireference tools for chemical discoveries is attributed to their ability of representing strongly correlated electronic structures of molecular complexes accurately. In many instances, multireference studies are performed for exploring chemical phenomena in spectroscopy, catalysis, and chemical bonding. The application of this level of theory is especially crucial for understanding chemicophysical processes associated with many transition metal-, lanthanide-, and actinide-based systems, owing to their highly correlated electronic structures. Furthermore, due to the high accuracy of multireference theoretical predictions, they are often conjoined with experimental investigations for validating experimental observations as well as tuning and guiding experiments. With today’s easily accessible high-performance computing power, the theoretical multireference investigations of chemical species have accelerated. Hence, aiming to highlight the ongoing multireference quantum chemical efforts in various fields of chemistry and physics, the current Special Issue is established.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
