Title: Theoretical Structures of Molecules: Multiple Bonds
Author: Hampel, F.
Editor: von Ragué Schleyer, P.
Source: Landolt-Börnstein, New Series
Volume: II/22a
Year: 1993
ISBN: 3-540-56331-8
ISBN: 978-3-540-56331-0
Internet Resource: DOI:10.1007/b48045
RefComment: VIII, 193 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.

Title: Densities of Liquid Systems: Densities of Binary Aqueous Systems and Heat Capacities of Liquid Systems
Author: D'Ans, J.; Surawski, H.; Synowietz, C.
Editor: Schäfer, Kl.
Source: Landolt-Börnstein, New Series
Volume: IV/1b
Year: 1977
ISBN: 3-540-08272-7
ISBN: 978-3-540-08272-9
Internet Resource: DOI:10.1007/b20004
RefComment: 62 figs., VII, 335 pages. Hardcover
Abstract: Volume IV/1 contains information on the densities of liquid systems. It may be considered as a supplement to volume II/1 of the 6th Edition, which contains only a few data on nonaqueous systems. Data are not listed for all systems but primarily for those of greater interest where data for a larger range of concentrations were available.
