• Short: II/22b Title: Theoretical Structures of Molecules: Small Rings Author: Hampel, F. Editor: von Ragué Schleyer, P. Source: Landolt-Börnstein, New Series Volume: II/22b Year: 1994 ISBN: 3-540-56332-6 ISBN: 978-3-540-56332-7 Internet Resource: DOI:10.1007/b48044 RefComment: VIII, 160 pages. Hardcover Abstract: Volume II/22 presents computed geometries. Quantum chemical computations provide an excellent alternative to experimental methods for the determination of accurate structures of polyatomic molecules. The objective is not to duplicate, but rather to complement the existing literature. An advantage of computational chemistry over experimental methods is the possi-bility to obtain reliable geometries of molecules, even of important systems, which are difficult to synthesize, isolate, and to study experimentally.
• Short: II/25C Title: Structure Data Of Free Polyatomic Molecules: Molecules containing Three or Four Carbon Atoms Author: Graner, G.; Hirota, E.; Iijima, T.; Kuchitsu, K.; Ramsay, D.A.; Vogt, J.; Vogt, N. Editor: Kuchitsu, K. Source: Landolt-Börnstein, New Series Volume: II/25C Year: 2001 Keyword: Free Polyatomic Molecules; Carbon Atoms; Molecules ISBN: 3-540-66774-1 ISBN: 978-3-540-66774-2 Internet Resource: DOI:10.1007/b71431 RefComment: VIII, 481 pages. Hardcover Abstract: This volume contains data on the geometric parameters (internuclear distances, bond angles, dihedral angles of internal rotation etc.) of free polyatomic molecules including free radicals and molecular ions. This survey on structure data is made of four subvolume, each containing the geometric parameters determined in the gas phase either by an analysis of the rotational constants (and sometimes the vibrational constants) obtained from microwave, infrared, Raman, electronic and photoelectron spectroscopy or by an analysis of electron diffraction intensities. Most of the structures listed in the tables are for molecules in the electronic ground state,
