Abstract

The first infrared hole burning spectrum of a gas-phase neutral peptide not containing an aromatic amino acid is presented. In the model peptide Z–Pro–NHMe, the amide I and II bands in the 1500–1800 cm−1 region appear to be a clear diagnostic for the secondary structure of the backbone, while the analysis of a series of coupled CH bending modes in the 1000–1500 cm−1 region allows to distinguish between different possible orientations of the chromophore. The geometry of the peptide is strongly constrained by the proline and only one conformation of the backbone is observed, which is identified as a hydrogen bonded γ-turn.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
