Application of Infrared Spectroscopy for the Prediction of Color Components of Red Wines
A review of the application of IR spectroscopy for the analysis of color components in winemaking, and the contribution of spectral preprocessing to improve the multivariate calibration.
Andrea Versari, Giuseppina Paola Parpinello, and Luca Laghi
Confocal Raman Microscopy in Forensic Pharmaceutical Investigations
Confocal Raman microscopy can identify particles in the 5–50 µm range and can bridge the gap between micro-FT-IR and SEM-EDS analyses.
Mary A. Miller, Michelle R. Cavaliere, Ming Zhou, and Pronda Few
Nanoscale IR Spectroscopy: AFM-IR — A New Technique
By combining atomic force microscopy (AFM) and infrared (IR) spectroscopy, one can attain spatial resolution improvements of two orders of magnitude over traditional IR spectroscopy.
Curtis Marcott, Kevin Kjoller, Michael Lo, Craig Prater, Roshan Shetty, and Alexandre Dazzi
