โฆ Synopsis
The scanner observations of periodic Comet Halley (1982i) have been presented in the wavelength region XA3200-7000 w for three nights during pre-perihelion period. Emission features due to NH, CN, CH, C,, C,, and NH, molecules have been identified. The abundances and production rates of CN and C, species have been estimated.
