Summary From retention indices of fifteen polycyclic methylpolysiloxanes the selection of the proper structures for each of these compounds has been attempted. The fifteen substances were structural and geometric (cis-trans) isomers of compounds of five different elementar compositions. The retention indices were considered as the sums of increments representing the characteristic atomic groups, further the structural characteristic the molecules. Calculated structural increment — |S| —values turned out to be nearly identical for certain groups of the investigated molecules. Using a phase dependent increment for one of the characteristics atomic groups, the grouping of the measuring points was similar on all of the stationary phases involved. This fact, and some principles derived from the structural characteristics of the polycyclic methylpolysiloxanes formed the basis for the proposed structural identifications.
