  • Title: Analyzing NMR shielding tensors calculated with two-component relativistic methods using spin-free localized molecular orbitals.
    Author: Autschbach J.
    Journal: J Chem Phys; 2008 Apr 28; 128(16):164112. PubMed ID: 18447426.
    Abstract:
    A recently developed analysis method [J. Chem. Phys. 127, 124106 (2007)] for NMR spin-spin coupling constants employing two-component (spin-orbit) relativistic density functional theory along with scalar relativistic natural localized molecular orbitals (NLMOs) and natural bond orbitals (NBOs) has been extended for analyzing NMR shielding tensors. Contributions from a field-dependent basis set (gauge-including atomic orbitals) have been included in the formalism. The spin-orbit NLMO/NBO nuclear magnetic shielding analysis has been applied to methane, plumbane, hydrogen iodide, tetracholoplatinate(II), and hexachloroplatinate(IV).
