Modeling NMR chemical shifts: A comparison of charge models for solid state effects on 15 N chemical shift tensors

This paper presents results from applying different point charge models to take into account intermolecular interactions to model the solid state effects on the 15 N NMR chemical shifts tensors. The DFT approach with the BLYP gradient corrected exchange correlation functional has been used because i...
