Recent observations in the ultraviolet and infrared, particularly during the apparition of Comet Kohoutek, have considerably increased our knowledge of comets. New atomic and ionic species (H, C, O, and C(+)) have been identified with ultraviolet instruments on spacecraft. Improved observations of the OH radical in the near ultraviolet have been made from space and from high-flying airplanes. Recent ground-based infrared measurements indicate that cometary dust is very similar to that in the interstellar medium. Large regions of the infrared will be opened up when infrared instruments are operated in space, making it possible to detect the more abundant parent molecular species such as H2O and CO2. Other expected atoms and molecules such as N, CO, and H2 will be detectable in the ultraviolet.
