        Infrared spectroscopy
        Infrared spectroscopy can be used to identify certain functional groups in an organic compound.
        The wavelengths which are absorbed to cause the vibrations (stretches and bends) will depend on the type of chemical bond and the groups or atoms at the ends of these bonds.
        In infrared spectroscopy, infrared radiation is passed through a sample of the organic compound and then into a detector which measures the intensity of the transmitted radiation at different wavelengths.
        Infrared absorbances are measured in wavenumbers, the reciprocal of wavelength, in units of cm⁻¹.
