Sažetak
Morgan-trees (MTs) are a subclass of physical trees. Because their number is much less than the number of physical trees, MTs can be used for generating acyclic isomers of alkanes and alkyl derivatives. In this paper we have summarised the properties of MTs, devised a new method to obtain the recurrence formula accounting for the number of various MTs containing N vertices, and finally derived an analytical expression for this formula. In addition the method of deleting redundant structures was discussed.
