Accuracy of Rotational Parameters Predicted by High-Level Quantum-Chemical Calculations: Case Study of Sulfur-Containing Molecules of Astrochemical Interest.
TL;DR: The accuracy of rotational parameters obtained from high-level quantum-chemical calculations is discussed for molecules containing second-row atoms and the effects on computed rotational constants due to extrapolation to the complete basis-set limit are analyzed.
Journal ArticleDOI
Noncovalent Interactions and Internal Dynamics in Pyridine-Ammonia: A Combined Quantum-Chemical and Microwave Spectroscopy Study
Lorenzo Spada,Nicola Tasinato,Fanny Vazart,Vincenzo Barone,Walther Caminati,Cristina Puzzarini +5 more
TL;DR: This work represents the first application of an accurate yet efficient computational scheme, designed for the investigation of small biomolecules, to a molecular cluster.
Journal ArticleDOI
Molecular Line Parameters for the “MASTER” (Millimeter Wave Acquisitions for Stratosphere/Troposphere Exchange Research) Database
Agnes Perrin,Cristina Puzzarini,J.-M. Colmont,C. Verdes,Georges Wlodarczak,Gabriele Cazzoli,Stefan A. Buehler,Jean-Marie Flaud,Jean Demaison +8 more
TL;DR: In this article, a line-by-line database was generated in order to meet at best the needs of the MASTER (or MARSCHALS) instrument, including line positions, line intensities, line broadening and line shift parameters in the 294-305, 316-325, 342-348, 497-506 and 624-626 GHz spectral microwindows.
Journal ArticleDOI
Hyperfine structure of the J=1←0 transition of H35Cl and H37Cl: improved ground state parameters
TL;DR: In this paper, the Lamb-dip technique was used to resolve the hyperfine structure due to 35 Cl or 37 Cl and H. The present observations allow to provide not only very accurate hyperfine constants but also, joint together with previous data, the most accurate ground state rotational parameters known up to now.
Journal ArticleDOI
Rovibrational energy levels and equilibrium geometry of HCP
TL;DR: In this paper, the ground state potential energy surface for HCP has been investigated theoretically and a large fraction of electron correlation is included by multireference internally contracted configuration interaction from CASSCF reference wave functions using large orbital expansions.
