Chemistry Resources: Property Data

A guide to SU Library chemistry resources.


Tips for Property Searching

  1. Search under all synonyms for the property. Example: dissociation constant or pKa or ionisation constant or ionization constant
  2. Determine property symbol and/or unit.
  3. Try searching for a substance by CAS registry number, chemical name, molecular formula, and/or structure.
  4. If searching by chemical name, use various names: Chemical Abstracts (direct or inverted), IUPAC (direct or inverted), common, trade.
  5. If searching by molecular formula, know how molecular formulas are alphabetized in your source.
    Organic compounds: Carbon, Hydrogen, others in alphabetical order
    Inorganic compounds: May not be indexed as written
    Polymers: Try monomer
    Example: CHNO or HOCN
    Example: KBr or BrK
    Example: SO2Cl or Cl2OS
  6. Search under the subject area as well as the property name. Example: If looking for extinction coefficient, also try UV
  7. In print sources, search by using one or more of the indexes. Example: Dictionary of Inorganic Substances has four indexes: Structural Type, Name, CAS Registry Number, and Element
  8. Use the correct truncation symbol when searching online databases.
  9. If you can't find your property data using these resources, try a RESEARCH TOPIC search in SciFinder Web. SciFinder Web's natural language searching is useful for retrieving obscure terminology.

Elemental Data

NIST Periodic Table

  • NIST Elemental Data Index includes basic information about elements, atomic spectroscopy, atomic data, x-ray absorption, and nuclear data.
  • The Periodic Table of Videos provides a short, informative video about each element and molecular videos featuring popular molecules and compounds. These videos are created by video journalist Brady Haran, featuring real working chemists from the University of Nottingham.

Spectra and Spectral Data

Spectra can also be found in many of the other electronic resources linked on this page. Below are a few specialty websites.
