## Abstract The ^13^C and ^1^H NMR spectra of monofluorotryptophans and difluorotryptophans in methanol‐__d__~4~ were assigned based on 1D and 2D NMR techniques. Fluorine substituent effects on the chemical shifts (SCS~s~) of tryptophan were calculated and compared with those for indole. The fluori
