absorption band A series of very closely spaced absorption lines resulting from the absorption of light by molecules. Bands caused by titanium dioxide and carbon compounds occur in the spectra of low temperature stars (see M stars), including red giants. So-called diffuse interstellar bands, most likely due to complex carbon molecules, are observed in the spectra of remote stars.
