An extensive survey of the Raman spectral activity of a wide variety of carbon materials has produced experimental evidence for at least five structure‐sensitive lines or bands. In addition to the well‐known, always present 1580 cm −1 graphite line and the 1360 cm −1 disordered carbon line, there is a disorder line at ∼1620 cm −1 that is responsible for the apparent blue‐shift of the graphite line in very disordered carbons; and there are lines at ∼2700 and ∼2735 cm −1 that are strong in graphite and annealed carbons but absent in very disordered carbons. These additional lines increase the capability of Raman spectroscopy to characterize carbon materials.
