✦ Synopsis

Dendrimeric and related molecules that have the same atomic connectivity from exterior to core, P-C 1 -J 1 -C 2 -. . . Z (P peripheral group, J juncture, C connector, Z core) can be described completely by a highly compact fractal notation, which is of the general form Pf J1,J2 . . . (C 1 .C 2 . . . )Z. In this paper, we show how to describe molecules that deviate slightly from the symmetry of a related parent molecule, by use of parenthetic expressions (iX), (dX), and (YrX) which designate atoms or molecular groups that are inserted, deleted, or replaced by other groups in the parent.
