要旨

A cold, continuous, high flux beam of benzonitrile has been created via buffer gas cooling. The beam has a typical forward velocity of 67 ± 5 m s−1, a velocity spread of ±30 m s−1 and a typical flux of 1015 molecules s−1, measured via microwave spectroscopy. This beam represents the slowest demonstrated forward velocity for any cold beam of medium sized (>5 atoms) polyatomic molecules produced to date, demonstrating a new source for high resolution spectroscopy. The expected resolution of a spectrometer based on such beams exceeds current instrument-limited resolution by almost an order of magnitude. This source also provides an attractive starting point for further spatial manipulation of such molecules, including eventual trapping.

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.
