The ordered series of broad mass groups in thermal ion mass spectra from the coma of Comet Halley obtained with the Positive Ion Cluster Composition analyzer is examined. It is found that the series is characteristic of molecules rich in H, C, N, and O, and does not necessarily imply the presence of a long chain polymer, such as polyoxymethylene. It is suggested that the spectra resemble those of singly-bonded CH2, NH, O, and H units which are similar to the molecules detected in laboratory analogs of icy interstellar dust grains.
