• Short: II/25B Title: Structure Data Of Free Polyatomic Molecules: Molecules containing One or Two 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/25B Year: 1999 Keyword: Free Polyatomic Molecules; Carbon Atoms; Molecules ISBN: 3-540-63645-5 ISBN: 978-3-540-63645-8 Internet Resource: DOI:10.1007/b68834 RefComment: IX, 512 pages. Hardcover Abstract: Volume II/25 is a supplemented and revised edition of the preceding volumes II/7, II/15, II/21 and II/23 containing up to date information on inorganic and organic polyatomic molecules. All experimental methods for the determination of quantitative structural data of free molecules have been considered: microwave, infrared, Raman, electronic and photoelectron spectroscopy as well as electron diffraction. The data obtained by these methods have been critically evaluated and compiled. They are presented separately for each molecule, together with a schematic figure of the structure and the original literature.

Editor: Lechner, M.D. Source: Landolt-Börnstein, New Series Volume: III/38B Year: 1996 Keyword: organic compounds; refractive index; liquids ISBN: 3-540-60596-7 ISBN: 978-3-540-60596-6 Internet Resource: DOI:10.1007/b85533 RefComment: VII, 4210 pages, Hardcover Abstract: Volume III/38 Optical Constants provides critically evaluated data on refractive indices of inorganic and organic liquids and their wavelength dependence (dispension). Part A contains the inorganic, organometallic, and organononmetallic liquids, and the binary liquid mixtures (about 900 pure substances and their mixtures). Part B contains data of more than 7600 organic liquids.
