Professor Rohit Bhargava and his team at the University of Illinois, where they have established the Cancer Center at Illinois, are advancing research in tumor microenvironments, using techniques such as high-definition Fourier transform infrared (HD-FT-IR) coupled with machine learning. We recently spoke to Bhargava about this work.
Those inexperienced in using FT-IR spectrometers can encounter problems when measuring spectra. This article discusses several main issues that most users experience while using FT-IR spectrometers and how to remedy each problem.

Here, we finish a discussion of the spectrum of polyethylene (PE) and explore
how different PE syntheses produce materials with different physical and

Peak shifts in infrared spectra may occur for many reasons other than structural changes on the molecular or unit cell level. Here, we discuss several examples.
Igor K. Lednev at the University at Albany SUNY in New York explains advances in forensic analysis using a variety of chemometrics techniques to classify ATR FT-IR and Raman spectra of bodily fluids.
Infrared nanoscopy is a valuable new spectroscopy tool for exploring the nanoscale of materials science. Mun Seok Jeong of Sungkyunkwan University in Korea explains.
Inline FT-NIR and offline terahertz Raman imaging analysis are used to characterize active pharmaceutical ingredient (API) crystallinity and to monitor different solid physical states of the API, to control process parameters of hot melt extrusion.
Resonant SEIRA overcomes the limitations of traditional Fourier transform infrared (FT-IR) spectroscopy for minute sample sizes of relatively low absorptivity.
Frank Neubrech of Heidelberg University is exploring resonant SEIRA in applications such as monitoring dynamic processes and hyperspectral infrared chemical imaging.

Polymers contain practically every infrared functional group imaginable. Now that we understand infrared functional groups from previous articles, it is time to look at the spectra of polymers in greater detail.
