  1. How different is pyrimidine as a core component of DNA base from its diazine isomers: A DFT study?

    The question why nature chooses pyrimidine as a core component of DNA bases over other diazine isomers, that is, pyrazine and pyridazine, requires an investigation at the molecular level. In addition to being the most stable isomer, pyrimidine possesses unique properties including a single absorption band in the region of 200–300nm UV-Vis spectrum and s-like HOMO. Pyrimidine is also the preferred structure in the energy decomposition analyses with the favorite N[BOND]C[BOND]N bond revealed by graph theory.

  3. The electron delocalization range in stretched bonds

    Electron delocalization is fundamental to chemical bonding. Electron delocalization range function EDR ( inline image) quantifies the degree to which electrons at point inline image in a calculated wavefunction delocalize over distance d. The EDR illustrates electron localization in compressed bonds as well as delocalization, fractional occupancy, and left-right correlation in stretched bonds. The EDR also shows how simple mean-field theories over-delocalize stretched bonds, a delocalization error that is fixed in accurate multireference calculations.

    Multiscale modeling for interpreting nuclear magnetic resonance relaxation in flexible molecules

    Mirco Zerbetto and Antonino Polimeno

    Version of Record online: 9 AUG 2016 | DOI: 10.1002/qua.25215

    This tutorial review provides a comprehensive description of a multiscale integrated computational approach to the calculation of nuclear magnetic resonance relaxation data of flexible molecules in solution based on the definition, ab initio parametrization, and solution of a stochastic diffusive equation for a set of relevant molecular coordinates.
