Special Issue Information

Dear Colleagues,

The simulation of chemical reactions is the holy grail of quantum chemistry. Car–Parrinello molecular dynamics paved the way to the description of complex reactive systems, also including reactive solvents.  The basis is the on-the-fly approach, treating all nuclear degrees of freedom of a molecular system at once. However, almost 40 years after the development of the Car–Parrinello method, it is still difficult to describe reaction events from first principles unless the systems are small and the reactions are ultrafast. Bridging the time scales became possible with methods for the acceleration of chemical reactions such as metadynamics and chemical flooding. Attempts have been made to reduce the computational costs by using semiempirical methods or reactive force fields. Furthermore, big biochemical systems have been treated using the QM/MM approach. We welcome submissions from all these fields; not only applications, but also reports on method developments or technical developments.

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.

This paper deals with the stability and decomposition of a recently predicted noble-gas compound, HXeNH2. Despite natural progress and interest in noble-gas hydrides, little is known of their decomposition reaction. In this study, the dissociation reaction is explored by ab initio calculations and by Ab Initio Molecular Dynamics (AIMD) simulations. The results could be important for the future experimental search of the compound. It is found that the main decomposition channel is HXeNH2 → H+Xe+NH2. A key step in the reaction is found to be a rearrangement of the partial charges of the atoms involved. The results could be of significance also for reactions of other compounds with Xe-N chemical bond and other noble-gas hydrides. Full article
