The distribution of the CN and C3 bands at 388 and 405 nm in Comet Halley is analyzed to improve the understanding of their properties and origin in comets. The Monte Carlo method, which takes into account the solar radiation pressure and the daughter molecule ejection velocity, as well as variations of the nucleus activity, is further developed. The merits of the present observations are much better spatial resolution (a slit size of 25 x 1 arcmin), much smaller distances from the nucleus (down to 80 km), and a large number of the spectra (1043). The C3 production rate and its parent lifetimes, the photodissociation ejection velocity, the distance of unit optical depth for C3 formation, and properties of the CN 388 nm band are determined.
