The LDMs of the three rings of phenanthrene according to the labeling
Scheme 3.1 are [72]:
ð3:28Þ
ð3:29Þ
ð3:30Þ
Note that unlike the LDM of the full system, a partial LDM such as the ones
provided for the individual rings of phenanthrene above will generally not sum into
an integer number of electrons since the sum of sums now yields the population of
Scheme 3.1 Phenanthrene with its atom and ring labeling scheme
