Special Issue "Computational Spectroscopy"
A special issue of Mathematics (ISSN 2227-7390).
Deadline for manuscript submissions: closed (31 January 2019).
Interests: Quantum dynamics including method development to compute anharmonic vibrational spectra and multivariate potential energy surfaces; Theoretical modeling of processes in photoelectrochemical solar cells, specifically focusing on computational dyes design and non-adiabatic processes and effects due to nuclear dynamics; Computational modeling of metal-ion batteries with the focus on electrode materials for post-Li (Na, Mg) batteries and organic batteries; Large scale ab initio materials simulations based on orbital-free density functional theory and density functional tight binding, including method development in these; Modeling of molecule-surface interactions
Spectroscopies, probing electronic or vibrational transitions, are workhorse material characterization techniques. Optical absorption and luminescence measurements are ubiquitously used to characterize, e.g., materials used in solar cells, organic electronics, etc. Vibrational spectra are ubiquitously used to assign species, e.g., in catalytic reactions and of course in the atmosphere and outer space. Computed spectra are of great help to assign species, that is to say, when they are accurate.
In spite of significant differences between vibrational and electronic spectroscopy, there are also similarities and possibilities of cross-fertilization. Computed vibrational and electronic spectra follow from or approximate solutions to, respectively, vibrational and electronic Schrödinger equations. The commonly used approximations are still relatively inaccurate or costly; for example, species assignment in aggregate states and at interfaces still largely relies on the harmonic approximation to vibrational spectra.
In this Special Issue, we attempt to bring together works that aim to solve vibrational, electronic, or related versions of the Schrödinger equation (such as the Kohn-Sham equation) or equations used in other applications with ideas portable to computation of vibrational or electronic spectra. We would like to juxtapose ideas that can be used in these two applications. We welcome papers addressing the issues of coupling of degrees of freedom, basis size and completeness, selection of quadrature and collocation grids, use of rectangular matrices, approximations to calculations of excitations, etc.

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 papers will be 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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Mathematics 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 1600 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.
