## Abstract __N__‐Alkyl‐__N__‐tosyl amino acid esters were ionized by fast atom bombardment (FAB) in a nitrobenzyl alcohol matrix through oxidative processes leading to molecular radical cations (M^+·^). The addition to the matrix of Cu^11^ salts induces the ionization through proton attachment whe

## Abstract The formation of cryptophane‐A (C1) and the deuterated cryptophanes C2–C6 from their respective precursors P1–P6 in a mass spectrometer ion‐source was evidenced by liquid secondary ion mass spectrometry (LSIMS). Mass‐analyzed ion kinetic energy experiments performed on the precursor mol

## Abstract Proton transfer reactions were studied in all titratable pairs of amino acid side chains where, under physiologically reasonable conditions, one amino acid may function as a donor and the other one as an acceptor. Energy barriers for shifting the proton from donor to acceptor atom were
