Abstract
Among all catacondensed benzenoid molecules the unbranched systems pos sess the largest number of spanning trees. Some other relations for th e spanning-tree count of catacondensed benzenoids are also reported. T he results obtained continue to hold for catacondensed molecules compo sed of rings the size of which differ from six. The propositions repor ted do, however, depend for their validity on there being rings of onl y one size in the catacondensed system under study.
