Useful sites for organic chemistry:

The following sites offer some useful tools for studying organic chemistry: 

• ChemFinder - reference database (includes Merck Index) that provides information on chemical formulas,structures, synonyms, reactivity, hazards, physical properties, mp, bp, etc. 
• Electronic Organic Chemistry Flashcards - flashcards for studying reactions of alkenes, alkanes, alkynes, alcohols, aromatics, aldehydes and ketones, and thiols.

The following sites offer links to a variety of other organic chemistry resources:

• Organic Chemistry Directory

Useful sites for spectroscopy:

• Organic Chemistry OnLine Spectroscopy Tutorial - an excellent site for practicing spectroscopy problems; includes IR, ¹H- and ¹³C-NMR, mass spectrometry, combined problems.
• Galactic Data Viewer - you can download an IR/NMR spectral viewer for free! Once downloaded, you can view the IR or NMR spectrum if you have any of the following: CAS number, compound name, or molecular formula.
• Integrated Spectral Database for Organic Compounds  an excellent site to view various spectra.
• NIST – huge database of spectra for organic molecules.
