摘要
The morphology of epsilon-caprolactam has been predicted using a periodic bond chain analysis. Two kinds of building units have been considered: monomers and dimers. The most important forms according to the monomer analysis are {111BAR}, {110}, {200}, {111} and {311BAR}. The dimer analysis gives the {200}, (201BAR}, {111BAR} and {110} forms as the most important ones. The results of the analyses are compared with the morphology of caprolactam grown from the melt and from fifteen different solvents.
