that, since we define the BEC for each atom as one-third of the trace of its BEC tensor, the larger mean BEC value for (5,1) than for (4,1) hypervalent units may arise simply due to averaging over two hyperbonding directions rather than one for the (4,1) units. In any case, ...
4.8. Dipole moment ( 0), mean polarizability (˛0), anisotropy of polarizability ( ˛) and first hyperpolarizability (ˇ0) First hyperpolarizability is a third rank tensor that can be described by a 3 × 3 × 3 matrix. The 27 components of the 3D- matrix can be reduced to 10 ...

This leads to the expression of the general thermodynamic potential (ψ) and the Piola-Kirchhoff stress tensor (S) as the additive superposition of an elastic part related to the deformation of fibres and a viscous part related to the flow of matrix described above. The resultant expression is...

The essential requirement for large bulk EO response is that the active component chromophore has a large microscopic molecular first hyperpolarizability tensor (β), and the quest for such chromophores has been a very active research field. To date, the vast majority of effective EO chromophores ...
