ChemFinder
Provides searching for compounds, their property data and 2D chemical structures.

Chemindex
A guide to more than 130,000 chemicals. Entries contain name, synonyms, RN, and a list of databases containaing information about the chemical.

Chemistry WebBook
Includes thermochemical data; IR, mass, UV/Vis, and elctronic and vibrational spectra; constants for diatomic molecules; ion energetics and thermophysical property data. May search this database by names, formulas, RN's, molecular weight, and spectral properties.

Elements
Provides property data for the elements.

Minerology (ATHENA)
Includes systematic lists of minerals, pictures of minerals, and searching capability by names or formulas.

Organic Compounds Database
May be searched by melting and boiling points; by index of refraction; molecular weight; formula; mass spectral peaks; etc.

Physical Reference Data
Contains spectroscopic, ionization, radiation dosimetry, nuclear physics, etc. data.

Properties of Water

RiskWare: Hazardous Chemicals MSDS
Contains physical and chemical property data, toxicology data, and a hypertext version of the MSDS substances.

ThermoDex
An index of thermodynamic and thermophyscial data of chemical compounds found in some thermodynamic data handbooks. Boiling point, heat of vaporization, viscosity, activity coefficient, azeotropic data, bond dissociation energy of elements, gases, acetone, air, benzene, etc. may be searched. CRC handbook, Beilstein, Londolt-Bönustein online datafiles are not indexed.

WebElements
An online periodic table. For each element provides 25 categories of information. Includes graphical representation of properties.

Yale University
Chemistry web page contains links to "Finding Information on a Know Substance" and "Searching for Compounds Using Property Information". Chemical properties, registry number (RN), spectral information (NMR, IR, Raman, UV), use, etc. may be searched.
