WebThe peaks show areas of the spectrum where bonds are vibrated. The IR spectrum of a molecule can be expressed as a function of wavelength. For example, in the case of water, the wavelength of light emitted from the water molecule is about 380 nanometers (nm). This wavelength corresponds to a wavelength range of about 0.1 to 1.5 micrometers (μm).
