Microsolvation Effects on the Excited-State Dynamics of Protonated Tryptophan

To better understand the complex photophysics of the amino acid tryptophan, which is widely used as a probe of protein structure and dynamics, we have measured electronic spectra of protonated, gas-phase tryptophan solvated with a controlled number of water molecules and cooled to ∼10 K. We observe...
