Abstract

The pure rotational spectra of the astrophysically important monosubstituted HC3N-isotopomers HCC13CN, HC13CCN, H13CCCN and HCCC15N in their ground and various vibrationally excited states, which will be denoted (4, 5, 6, 7) hereafter, have been studied extensively in the 2 mm region. Transitions of the ground vibrational states and vibrational satellites appendant to the two lowest bending fundamentals 6 and 7 have been measured up to 625 GHz. The Fermi resonance system (0,1,0,0)/(0,0,0,3) has been analyzed for the HCC13CN and H13CCCN isotopomers for the first time. Furthermore, pure rotational transitions of the four doubly substituted isotopomers HC13C13CN, H13CC13CN, H13C13CCN and HCC13C15N could be detected for the first time, not only in the ground but also in vibrationally excited states. This work is to provide accurate the astronomical community.

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.
