List of useful chemistry links
- American Patents can be searched at the US Patent Office (USPA). The
interface is allows very sophisticated full text searches. Patents can
be downloaded as ASCII files as well as graphics. The graphic version
is using the Tagged Image File Format (TIFF). Displaying them requires
either a TIFF G4 plug-in for the browser, or a properly installed and
configured application to which the browser sends the TIFF images for
display. Unfortunately, relatively few image viewers and plug-ins
handle G4 compression.
- Via esp@cenet
European patents (both EP and patents at the member states) as well as
WO, Japanese (PAJ) and worldwide patent documents are available.
- Japanese patents are also available from the Japanese Patent Office.
- Not just for chemistry a good starting point: Google Scholar.
- ChemExper is an
on-line catalog of chemical suppliers. It allows you to find a chemical
by molecular formula, name, CAS number, substructure or physical
- The NIST WebBook will
provides to the full array of data compiled and distributed by NIST
under the Standard Reference Data Program. The links are not
highlighted, so it takes a little time, to find the right points to
- You don't know what's behind the abbreviation of a chemical
can give you the answer.
- The Brookhaven Protein
Database offers now a WWW service; the database is really big. There is
another query interface at the NIH.
- The EXTOXNET
InfoBase with information about pesticides.
- The BioMagResBank
provides information about NMR spectra of proteins, peptides, and
- The NDB (Nucleic
Acid Data Base) provides structural information about nucleic acids.
- A number of interesting databases are found at the RIO-DB of AIST
(Agency of Industrial Science and Technology, Japan).
- Very interesting is the Organic
Compounds Database from Harold M. Bell at Virginia Tech. The layout is
not great, but who cares?
- Demonstrators and research prototypes for Internet-based
chemical information services at the University
- A list of physical
reference data at the National Institute of Standards and Technology
including fundamental physical constants and atomic spectroscopic data.
- For the visualization of chemical structures: RasMol (several
systems, highly recommended).
- An excellent tool for visualization under Xwindows is molden. Files from the Ab
Initio packages GAMESS-UK , GAMESS-US and
GAUSSIAN and the Semi-Empirical
packages Mopac/Ampac can be used as input. Output is possible for
example in povray format for high
- Collections of chemistry related software at ChemDex.
- The e-textbook from Joseph Hornak
(Rochester Institute of Technology) is a very good (and free!! :-) )
introduction into NMR spectroscopy.
- The WebElements is
the classical on-line periodic table.
- The ChemPuter
includes calculations of isotope patterns, element percentage,
oxidation state and electron accountancy for metals in a complex. Very
- Interesting is the Chemistry
Hypermedia Project at Virginia Polytechnic Institute and State
