The interpretation of Raman spectra is discussed for a series of functionalized celluloses.

The results from the experiment in the second laboratory are calculated and examined.

A method is presented using IR and Raman microscopy to discriminate carbonate-containing and carbonate-free PVC that helps forensic scientists trace suspects, avoid wrong certificates of authenticity, and characterize and analyze carbonate components.

What role can mid-infrared (mid-IR) spectroscopy play in protecting the environment and human health? That is precisely the question being addressed by Mid-Infrared Technologies for Health and the Environment (MIRTHE), a National Science Foundation-Engineering Research Center founded in 2006 at Princeton University (Princeton, New Jersey) and five partner institutions.

The use of Fourier transform infrared (FT-IR) and Fourier transform near infrared (FT-NIR) spectrometers now accounts for the majority of demand for mid- and near-infrared instruments, with demand from the petrochemical industry beginning to follow the trend. The major instrument vendors as well as specialist suppliers compete strongly in the petrochemical segment of the market, which accounts for only a small percentage of the overall FT-IR and FT-NIR markets.

Short Courses

Here, Maxwell's fourth equation of electrodynamics and how light is described in terms of Maxwell's four mathematical expressions is examined.
