Reliable computations of NMR and EPR spectroscopic parameters for flexible molecules in condensed phases require a proper account of stereo-electronic, dynamic, and environmental effects. In the framework of density functional theory methods, these effects can be introduced by second-order vibrational perturbation theory and polarisable continuum models. Two test studies illustrate potentialities of the integrated computational approach we have developed in the last years for these purposes.

Abstract

Reliable computations of NMR and EPR spectroscopic parameters for flexible molecules in condensed phases require a proper account of stereo-electronic, dynamic, and environmental effects. In the framework of density functional theory methods, these effects can be introduced by second-order vibrational perturbation theory and polarisable continuum models. Two test studies illustrate potentialities of the integrated computational approach we have developed in the last years for these purposes. Further extensions to mixed discrete-continuum models and stochastic approaches for long-time dynamical effects are also sketched.
