Starting Page for Infrared Spectroscopy

 

What's on this page?

I tried to make a collection of useful links for infrared spectroscopist dealing with the basics of infrared, interpretation of infrared spectra, correlation charts and window material data. From this page, almost every website available on the internet concerning infrared can be reached.

You could not find what you are looking for? Click here to go to the extensive list from The Internet Journal of Vibrational Spectroscopy with links to manufacturers, optics, accessories, educational resources, software, research groups and societies around the world, journals, spectra, references and utilities. Or go here, where more links can be found to all infrared sites.
