Abstract
The λ2 200 Å interstellar absorption band, generally attributed to graphite grains, could equally well arise from π→* electronic transitions in conjugated double bonds of organic molecules. These molecules, which should comprise ∼ 10% of the total interstellar dust mass, may be lodged within clumps of 100 Å-sized refractory grains.
