Instrumentation and development of a mass spectrometry system for the study of gas-phase biomolecular ion reactions
… system described above, a new reaction between protonated alkyl amines and pyrolysis formed cyclopropenylidene carbene was discovered, as the first experimental evidence of the reactivity of cyclopropenylidene. Given the important role of cyclopropenylidene in the combustion chemistry, organic …

Theoretical And Experimental Studies Of Noncovalent Metal Cation Binding And Base Pairing Interactions Of Cytosine And Modified Cytosines
… </p> <p> The base-pairing interactions of the proton-bound dimers of cytosine are likely the major factor that helps stabilize noncanonical DNA <i>i</i>-motif conformations, which are associated with Fragile X syndrome, the most widespread inherited cause of mental retardation in humans. …

Thermochemical differences in lysine and lysine-homolog containing oligopeptides: Determination of basicity and gas-phase structure through mass spectrometry, infrared spectroscopy, and computational chemistry
… di-, tri-, and tetra- peptides containing a proton-accepting probe: lysine and or the non-proteinogenic lysine-homologs: ornithine, 2,4-diaminobutyric acid, and 2,3-diaminopropionic acid. Peptides were studied in isomeric pairs for which the basic amino acid was placed closest to the …
