In contrast the phenyl groups bonded to the hydrazine are all almost perpendicular to the core plane by 88.46[degrees] for Empp-Ph, 89.24[degrees] for Prmpp-Ph, and 85.34[degrees] for Pmpp-Ph.

It was then dried at room temperature and recrystallised with absolute ethyl alcohol to give a white crystalline solid which was identified bis-p-methoxy phenyl phosphate.
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.sub.m] as a function of the dichroic ratio of the experimentally obtained out-of-plane vibration as
