title: Exhaustive generation of organic isomers. 6. Stereoisomers having isolated and spiro cycles and new extended N_tuples.
abstract: A new stereoisomer generation system named CAMGEC2 for generation of stereoisomers containing isolated and spiro cycles with one or more descriptors among R, S, Z, E, M, and P is developed using Graph Theory. It includes new approaches for symmetry analysis, cycle detection processes in molecular graphs in a modular way, and also an extension of the N_tuple format for linear representation of molecular graphs that keeps graph topographical information.
