Beskrivelse
In my presentation I will discuss the effect of weak molecular interactions on the two NMR parameters: the nuclear magnetic shielding and indirect nuclear spin-spin coupling constants. I will first discuss the performance of density functional theory in describing the hydrogen bonding effects on NMR shielding constants in the water dimer and a complex of formaldehyde with two water molecules [1] and on NMR indirect nuclear spin-spin coupling constants in the hydrogenfluorid dimer, water dimer and the ammonia-water complex [2]. In the second part I will discuss the changes in the NMR indirect nuclear spin-spin coupling constants of difluoroacetylene in complex with one or two hydrogenfluorid molecules [3]. Finally, I intend to discuss the NMR chemical shifts of noble gases in noble gas dimers [4] and complexes with fullerenes [5].References:
