Inside Back Cover: Measurement of Nanometer Distances in Solution via ¹³C NMR Spectroscopy—Shrinking of Macrocycles with Increasing Temperature (Angew. Chem. Int. Ed. 25/2023)

The determination of nanometer-scale distances in solution is an enormous challenge. In their Research Article (e202301465) Gebhard Haberhauer and co-workers demonstrate that macrocycles can be measured using a molecular spring 13C-NMR spectroscopy. sensitivity the method even allows thermoelasticity at level: One studied system expands low temperatures shrinks high temperatures.
