The value of the phase difference between the induced dipole moment m, and the field vector E controls the magnitude of the torque, reaching maximum when the phase difference is 9"", and zero when the phase is zero.
The static first hyperpolarizability AYvec was calculated by M06-2X Method combined with FF(finite field method), which is more efficient and less expensive than other methods compared with, where AYvec represent the hyperpolarizability along the molecular dipole moment defined as follows:
Previously, the conformation of a repeat unit of uniaxially oriented atactic PSt was assumed; angle y between the transition dipole moment vector of the out-of-plane vibration of the phenyl ring and the chain axis was determined [25] by plotting the orientation function of the main chain [f.
