We demonstrate that the C-D transitions of the deuterated amino acid, leucine-d10 can serve as convenient structural reporters via dual-frequency 2DIR methods, and we discuss the potential of leucine-d10 and other amino acids with deuterium-labeled side chains as probes of protein structure and dynamics.
