C≡N stretching bands of Fmoc-L-TrpCN in THF and a water/THF mixture (60/40, v/v), as indicated. The concentration of Fmoc-L-TrpCN was estimated to be ~3.3 mM based on weight, and the optical pathlength was about 130 µm. For easy comparison, the spectrum measured in water/THF mixture has been scaled by a factor of 1.3.
