Spectroscopy (Chemistry)
Make your own spectroscope! 
Use basic household materials to make your own spectroscope. A spectroscope is a device that lets us find out what things are made of. It works by taking light and splitting it up into its component colors. Different elements make different colors when they glow. We can make objects and...
IR Spectroscopy 
Wikipedia's take on IR spectroscopy. Infrared spectroscopy (IR spectroscopy) is the spectroscopy that deals with the infrared region of the electromagnetic spectrum, that is light with a longer wavelength and lowerfrequency than visible...
Spectral Database for Organic Compounds 
Easily the most useful site I ever used during my Chemistry undergrad. AIST (Japan) put together a database of spectral analysis for anyone who needs to look up what a particular compound will look like under scrutiny. You can search by name, formula, weight, number of atoms, and certain NMR shifts...
