摘要: Abstract Using telescopic observations by ourselves and other observers, we have identified cyano-group containing molecules in the very dark solids on surfaces of a few D-class asteroids, dust some comets, low-albedo hemisphere Iapetus, rings Uranus, through spectroscopic detection 2.2-μm overtone CN stretching fundamental mode. The occurrence this band all four classes small Solar System bodies may be diagnostic duration exposure degree modification surface materials, also establish link between outer interstellar materials.
