During the encounter session of Vega 2 with comet Halley on 6 Mar. 1986, advantage was taken of the approach motion and of the resulting zoom effect to assemble the monochromatic charts produced by a three channel spectrometer in composite images at selected wavelengths. Two jets are clearly apparent in most of the monochromatic images. The OH and CN emission originating from the jets exhibit a pronounced peculiarity. The bands located at 309 and 388 nm show an excess of emission at 305 and 383 nm. The proposed mechanism, specific to the jets, is the photodissociation of one or several organic molecules of the type A-OH or B-CN which would release hot OH and CN when submitted to the solar UV flux. These organic molecules would be a component of the envelope of the CHON submicronic grains dragged by the gaseous jets. They provide an additional argument in favor of the similarity between cometary and interstellar matter.
