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 CN 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.
