The hydrogen-bonded dimer CH 3 NC...HCl has been isolated in a pulsed jet by keeping the reactive components CH 3 NC and HCl separate until the point at which they expand into the evacuated Fabry-Perot cavity of a pulsed nozzle Fourier-transform micr

Binding of aqueous dipeptides, GlyX and X'Gly (X = Leu, Phe, Pro, and Ala; X' = Leu and Phe), onto monolayers of dialkyl oligoglycyl amphiphiles has been investigated by n-A isotherm measurement, FT-IR spectroscopy, and XPS elemental analysis. Dipept

A molecular dynamics (MD) simulation was performed on the hydrated decapeptide Ala 10 .550H 2 O under periodic boundary conditions. The initial configuration of the peptide was a canonical right-handed α-helix. Over the course of the MD trajectory,

Ribonucleotide reductase (RNR) catalyzes the reduction of ribonucleotides to deoxyribonucleotides.1–3 Class I RNRs are composed of a 1:1 complex of two homodimeric proteins, α2 and β2. α2 contains the binding site for substrates and allosteric e

Experimental evidence for intramolecular blue-shifting C-H...O hydrogen bonding is presented. Argon matrix-isolation infrared spectra of 1-methoxy-2-(dimethylamino)ethane exhibit a band at 3016.5 cm-1. Spectral behavior with annealing indicates that

Anion-templated aqueous self-assembly resulted in the formation of an endohedrally functionalized FeII4L4 tetrahedron from azaphosphatrane-based subcomponents. This new water-soluble cage is flexible and able to encapsulate anions with volumes rangin
