Rotationally resolved electronic spectroscopy of tryptophol in the gas phase
文献信息
John T. Yi, David W. Pratt
High resolution S1–S0 fluorescence excitation spectra of tryptophol have been observed in the collision-free environment of a supersonic beam. Each origin band has been assigned to a unique conformer based on its observed rotational constants. Unlike its close relative tryptamine, which exhibits seven distinguishable conformers under similar conditions, tryptophol exhibits only four (GPy-in, GPh-in, and two anti structures). Possible reasons for this difference in behavior are discussed.

Physical Chemistry Chemical Physics

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.
