Tautomerism, a particular case of isomerism, plays an important role in modern organic
chemistry, biochemistry, medicinal chemistry, pharmacology, molecular biology, and life …

Amino acid and peptide radical cations, M.+, are formed by oxidative dissociations of [Cu
(auxiliary ligand)(M)]. 2+ and [MetalIII (salen)(M)]+ complexes. The most easily formed …

A photoionization mass spectrometry study in the 6–22 eV photon energy region of five
amino acids, glycine-h5 and its-d5 isotopologue, α-alanine, β-alanine, α-aminoisobutyric …

We present a combined experimental and theoretical study of the complex dynamics of
excited doubly ionized glycine molecules in the gas phase. Multicoincidence mass …

Glycine is the simplest amino acid, and due to the significant astrobiological implications that
suppose its detection, the search for it in the interstellar medium (ISM), meteorites, and …

The structure of glycine, alanine, serine and cysteine radical cations, as well as their Cα–R
fragmentations have been studied at the B3LYP/6-31++ G (d, p) level of theory. For all …

Accurate vertical (adiabatic) ionization potential (IP) and valence electron affinity (EA) of
glycinamide, including its possible conformers, have been determined employing density …

The dissociations of two types of copper (II)-containing complexes of tryptophan (Trp),
tyrosine (Tyr), or phenylalanine (Phe) are described. The first type is the bis-amino acid …

The conformational properties of ionized amino acids (Gly, Ala, Ser, Cys, Asp, Gln, Phe, Tyr,
and His) have been theoretically analyzed using the hybrid B3LYP and the hybrid-meta …

Hydrogen migration in the glycine cation has been investigated using a combination of a
short train of attosecond extreme ultraviolet pulses with few-optical-cycle near-infrared …
