Abstract
THERE has recently been renewed interest in the nature of interstellar grains. The model of a grain consisting of a graphite core surrounded by a dirty ice mantle adequately accounts for the wavelength dependence of interstellar extinction1 and interstellar polarization2. The question of the source of the large number of diffuse (but discrete) interstellar absorption bands, however, remains. A number of theories have been proposed to account for these bands3–5.
