Swan bands are a characteristic of the spectra of carbon stars, comets and of burning hydrocarbon fuels.[1][2] They are named for the Scottish physicist William Swan, who first studied the spectral analysis of radical diatomic carbon (C2) in 1856.[3]
Swan bands consist of several sequences of vibrational bands scattered throughout the visible spectrum.[4]
