Abstract: Recent advancements in high-resolution ion mobility separations have enabled separations of isotopologues and isotopomers, broadly termed as isotopic shifts, based on changes in their mass distributions (i.e., changes in their center of mass and moments… read more here.

DOI: 10.3390/molecules25122915
Abstract: Calculations of nuclear magnetic resonance (NMR) isotopic shifts often rest on the unverified assumption that the “vibration hole”, that is, the change of the vibration motif upon an isotopic substitution, is strongly localized around the… read more here.
