Vibrational Spectroscopy for Forensics

Forensic science

Forensic scientists analyze a large and varied range of criminal and legal evidence, with the aim of determining the identity or source of a sample. Fourier Transform Infrared (FTIR) spectroscopy and Fourier Transform Raman (FT-Raman) spectroscopy are extremely useful techniques in this endeavor. These analytical methods provide users the ability to obtain crucial chemical information about everything from counterfeit money or carpet fibers to soil samples or paint chips. Similarly, FTIR microscopy and Raman microscopy provide efficient and effective materials analysis for modern forensics laboratories, with the ability to focus on an even smaller area.

 

Whether you’re trying to screen and confirm known compounds or identify unknown substances, vibrational spectroscopy techniques like FTIR and Raman can provide you with essential chemical data. Thermo Fisher Scientific has the instrumentation you need to deliver forensic evidence that will stand up in court.

Take advantage of these documents and videos to increase your understanding of the ways vibrational spectroscopy can benefit forensic analysis. A compendium of notes on laboratory applications provides in-depth looks at specific cases where FTIR or Raman analysis revealed key insights, while recorded webinars demonstrate examples of practical usage.

Compendium: Forensic Analysis with Microspectroscopy: When what matters are microns and minutes

In this compendium on Forensic Analysis with Microspectroscopy, you can read about real-world applications and gain exposure to a cross-section of FTIR and Raman microscopy uses in busy forensic laboratories:

  • Finding the provenance of paint chips with microspectroscopic evidence
  • Proving a document was altered through an analysis of inks on paper
  • Characterizing single fibers from a crime scene, using micro-ATR
  • Analyzing historical artwork by Tintoretto from Venice, Italy
     

Trace evidence detection

Most materials require multi-dimensional analysis to provide the full picture. Using a combination of FTIR microscopes and FTIR spectrometers can identify materials such as paint, glass, fibers, and tapes.

Multi-component identification

Distinguish illicit drug isomers with GC-IR and analyze complex mixtures using multi-component search with Thermo Scientific OMNIC Specta Software.

Suspicious document analysis

High-profile courts cases—from securities fraud to murder investigations—often hinge upon suspicious documents, requiring comparison between inks or reference databases. Counterfeit currency detection also relies upon analysis of the inks as well as the paper itself. Speed and accuracy are essential in building cases and making them stick.
