Figure 30 presents a summary of our findings concerning the prevailing or characteristic rotational isomers in the vapour phase of sulphone molecules. Looking for a characteristic pattern, the following observation may he made. Staggered forms prevail while eclipsed forms appear to he predominant when two double bonds (one of them S=0) may take a syn orientation. This is a very rough qualitative statement only, however, and there remain many important questions unanswered. It may be of interest to list some of them.
