What is it about?

The relationship among molecular structures, hyperpolarizabilities and crystal structures of cyclobutenediones were discussed to predict optical non-linearity and its stereoscopic conformation in the crystal according to the two level model.

Why is it important?

The characterization of crystal will be decided by nature of the hydrogen bond energy and stereoscopic confirmation more than molecule dipole-dipole interaction.

Perspectives

molecule with second-order non-linearity tend to make asymmetric. But, hydrogen bond control to arrange the molecule.
