The Latest Applications in Raman Spectroscopy
In this article, the editors of Spectroscopy present an overview of the latest trend in Raman spectroscopy.
Raman spectroscopy is a versatile forensic analysis method. It enables both qualitative and quantitative analysis by measuring the frequency and intensity of scattered radiations, respectively (1). Raman spectra serve as unique fingerprints for a wide array of compounds, allowing simultaneous tracking of polymers in cell walls and analysis of their molecular composition and structure (2). Its sensitivity to subtle structural changes makes it valuable for comparative tests. Ongoing advancements in Raman techniques and instrumentation further enhance its significance in tissue discovery and characterization (2).
Raman spectroscopy remains a popular spectroscopic technique for analytical scientists. It can provide detailed information on the vibrational and rotational modes of molecules, offering insights into chemical bonding, crystal structure, and molecular dynamics. By measuring the energy shifts in scattered light, Raman spectroscopy can identify specific chemical bonds and functional groups within a sample, making it invaluable for materials characterization, pharmaceutical analysis, and forensic science (2). Its non-destructive nature and ability to analyze samples in various states, including solids, liquids, and gases, make Raman spectroscopy an indispensable tool for scientific research and industrial applications (2).
Spectroscopy has published several technical and news articles on the latest research in Raman spectroscopy. Below is a compilation of some of the most recent articles on Raman spectroscopy. To read more about the current and ongoing research being conducted using Raman spectroscopy, click here.
Monitoring Chemical Changes by Raman Spectroscopy
By: Fran Adar
Polymerization reactions typically involve the loss of a carbon double bond as the chain length is increased, and because the signals from π electrons are strong, the ability to follow this reaction until the end is quite good. However, setting up a polymerization experiment for demonstration purposes can be hazardous. Here, we will show the chemical and spectral changes that occur during the cure of a commercial epoxy.

New Spectroscopic Techniques Offer Breakthrough in Analyzing Ancient Chinese Wall Paintings
October 29th 2024This new study examines how spectroscopic techniques, such as attenuated total reflection Fourier transform infrared spectroscopy (ATR FT-IR), ultraviolet–visible–near-infrared (UV-Vis-NIR) spectroscopy, and Raman spectroscopy, were used to analyze the pigments in ancient Chinese wall paintings.
FT-NIR and Raman Spectroscopic Methods Enhance Food Quality Control
October 28th 2024A recent study showcases the potential of Fourier transform near-infrared (FT-NIR) spectroscopy and spatially offset Raman spectroscopy (SORS) in detecting raw material defects in hazelnuts caused by improper storage conditions. FT-NIR spectroscopy proved especially effective, while SORS offered complementary insights in certain scenarios. These spectroscopic methods could modernize the speed and accuracy of hazelnut inspections in the food industry.
Nanometer-Scale Studies Using Tip Enhanced Raman Spectroscopy
February 8th 2013Volker Deckert, the winner of the 2013 Charles Mann Award, is advancing the use of tip enhanced Raman spectroscopy (TERS) to push the lateral resolution of vibrational spectroscopy well below the Abbe limit, to achieve single-molecule sensitivity. Because the tip can be moved with sub-nanometer precision, structural information with unmatched spatial resolution can be achieved without the need of specific labels.
