“…Such an ionization-induced hydration site switching has been reported for several monohydrated amides (tFA 24,49, 50 , tAA 20,21,51 , N-(2-phenylethyl)acetamide) 52 and also for monohydrated 4-aminobenzonitrile, 22, 53 5hydroxyindol, 25,54,55 tryptamine, 56 aminophenol, 57,58 and phenylglycine. 59 The isomerization dynamics is investigated in section 3-3 by ps-TRIR spectroscopy.…”
