Complementary Polytopic Interaction

Quadrupolar interactions (termed complementary polytopic interactions by the authors) are also responsible for mesophase induction and modification in a series of disc-like materials (e.g. 2 and 3) as described by, for example, Bushby and co-workers [11-13]. 

The other classic example of the use of quadrupolar interactions was from the Leeds group, " " who coined the term complementary polytopic interaction to describe the phenomenon and to distinguish it subtly from other examples...
