Infrared spectroscopy is sensitive to the bonding occurring in a quartz molecule
because it can measure the vibrational energy related to the atomic masses of
silicon and oxygen, bond strength and bonding symmetry. As shown, a sample
potentially containing quartz is placed within an infrared light source. If any
quartz is present, the infrared light is absorbed at the wavelength
corresponding to these vibrations. The decrease in the amount of infrared light
reaching a detector placed behind the sample is a measure of the quartz present.
