##Intro##

This is a page to compile, share, and publish research about near-ultraviolet, visible, and near-infrared spectroscopy/spectrometry analysis techniques. Not all will be applicable to our DIY spectrometer, but many are a good starting point for investigation. **If you want to publish research, post it on the Public Lab site and you can add it here too.** 

Some of the below papers describe other types of spectroscopy such as mid-infrared (MIR) or Fourier-transform infrared (FTIR) and the data they present will not be compatible/comparable with that which we gather in the 400-900nm range. But their methodologies may be a useful reference for those looking to reach similar results in the range our instruments can detect.
