Summary
Retention indices of polycyclic methylpolysiloxanes were plotted in the SE-30 and Tween-60 two phase diagram. Experimental points of isomeric compounds were scattered around straight lines. On applying an adequate code system for the compounds under investigation, “subisomer-lines” could be fitted to the points belonging to those isomeric molecules, that showed identical code numbers. Based on this representation, many of former structural identifications were confirmed and some of them corrected.
