Bacteriorhodopsin (BR), halorhodopsin (HR), and rhodopsin (Rh) all belong to the class of seven-helix membrane proteins. For BR, a structural model at atomic resolution is available; for HR, diffraction data are available only down to a resolution of 6 A in the membrane plane, and for Rh, down to 9
## Abstract Dipeptides of different amino acids have been studied by NMR in aqueous solutions at different pH values. The results obtained are discussed in terms of the different contributions to the chemical shift of the Ξ±βCH protons.
