Analysis of Polymers Using FT-IR
Contributor: Paul Tschida, 2013
Source: https://www.intertek.com/polymers/testlopedia/ftir/
Content: This webpage gives a brief overview of the FT-IR and its usefulness in identifying polymers. There is information about the test procedure, sample size, and how to deal with contamination.
Reliability and Usefulness: This seems like a reliable website. Interek, the company that runs the site, provides quality and safety solutions to many companies and businesses around the world.

Infrared Spectroscopy: Fundamentals and Applications
Contributed by: Madison Wilson, 2013
Content: Has a lot of information on IR spectroscopy, such as molecular motion and other fundamentals about how IR spectroscopy works. Also discusses Fourier transform and peak assignments.
Reliability and Usefulness:  Seems reliable, provides references, and is relatively recent (2004). Is useful for understanding IR Spectroscopy and background information.
Contributed by: Terilyn Lawson, 2013
This website has information on the background of plastics, how it is made, components, application etc. It is a good place to find information for the introduction of your reports and to make predictions of the types of plastic used in your product.
This website is reliable and is a organization for companies that are in the plastic business.
Flow chart for plastic identification by burn test
website:  https://ides3221-2011.blogspot.com/2011/03/plastics-identification-charts.html
This flow chart demonstrates how the burn test can be used to identify different plastics.
Content: The link below contains a list of common polymers and also their FT-IR spectra.
Reliability/Usefulness: These spectra are provided by NICODOM Ltd. They proved useful reference spectrum for the experiment and good images for a report or poster
