Abstract: | The possibility that the organic molecules that have been found near comets could have formed by UV photolysis of interstellar ices was investigated by simulating this process in the laboratory. It is found that oxygen rich organics containing C-OH, C-H and C=O groups are readily produced in this way. These results indicate that part of the organic material in comets may have formed by UV irradiation of ices, either in the pre-solar nebula or in the interstellar phase. |
