Summary

General Uses

• Identification of all types of organic and many types of inorganic compounds
• Determination of functional groups in organic materials
• Determination of the molecular composition of surfaces
• Identification of chromatographic effluents
• Quantitative determination of compounds in mixtures
• Nondestructive method
• Determination of molecular conformation (structural isomers) and stereochemistry (geometri-
cal isomers)
• Determination of molecular orientation (polymers and solutions)

Common Applications

• Identification of compounds by matching spectrum of unknown compound with reference
spectrum (fingerprinting)
• Identification of functional groups in unknown substances
