Dear Sir,
How Does Isotopic Substitution Affect the Gas-phase Proton Affinity of Glycine? A Combined Experimental and Ab Initio Study
Recently there has been widespread interest in the fundamental properties and reactivity of gas-phase ions derived from biomolecules. For example, the proton affinities ( P A ) of amino acids' and several simple peptides' and the acidities of 19 amino acids have been determined.' Ab initio calculations can provide important structural insights into such experimental result^.^ We have shown that there is good agreement between
