A 20 K high resolution X-ray data set of L-Ala-L-Ala-L-Ala*1/2 H2O was measured using an ultra-low temperature laboratory setup, that combines area detection and a closed cycle helium cryostat. The charge density determination includes integration of atomic basins and topological

Despite the increasing relevance of characterizing local conformational distributions in the unfolded state, an unambiguous description of the role that solvation and the addition of certain cosolvents play in altering this ensemble has yet to emerge. Alcohol cosolvents, and specifically

We present the first infrared spectra of a mass-selected deprotonated peptide anion (AlaAlaAla) and its decarboxylated fragment anion formed by collision induced dissociation. Spectra are obtained by IRMPD spectroscopy using an FTICR mass spectrometer in combination with the free electron

The structural analysis of natural protein fibers with mixed parallel and antiparallel beta-sheet structures by solid-state NMR is reported. To obtain NMR parameters that can characterize these beta-sheet structures, (13)C solid-state NMR experiments were performed on two alanine tripeptide samples:

Infrared multiple photon dissociation (IRMPD) spectroscopy is used to identify the structure of the b(2)(+) ion generated from protonated tri-alanine by collision induced dissociation (CID). The IRMPD spectrum of b(2)(+) differs markedly from that of protonated cyclo-alanine-alanine, demonstrating that the
