Unlocking Chemical Insights: FT-IR Spectroscopy Analysis for Efficient and Safe Material Identification

Learn about the informative power of Fourier Transform Infrared (FT-IR) spectroscopy, a non-destructive and rapid analysis method. This technique offers direct sample analysis, minimal sample preparation, and database matching for unknown compound identification. By utilizing chemical functional group strengths or spectral characteristics, FT-IR enables quantitative analysis without chemical reagents, environmental pollution, or safety hazards.

O H H -C-H 2850-2960 cm-1 -C=O 1640-1750 cm-1 =C-H 3020-3100 cm-1 -C-O 1050-1150 cm-1 -C=C- 1650-1670 cm-1 -O-H 3400-3640 cm-1 -C-Cl 600-800 cm-1 -N-H 3310-3500 cm-1 -C-Br 500-600 cm-1 IR Spectroscopy measures the radiation absorbed by materials due to molecular vibrations • Vibration frequencies are influenced by • Atom Size • Environment • Bond Strength ….provides a vast amount of chemical information

  4. Why Use Infrared Spectroscopy? Fourier Transform InfraRed (FT-IR) spectroscopy is an extremely powerful technique for identifying the molecular composition of many organic and inorganic materials. When analysed by infrared spectroscopy, materials produce a spectrum or fingerprint.
