of polymer dispersed liquid crystals,
Phys. Rev. E, 60, 4219-4225 (1999)
We present the calculation of NMR line shapes, including dynamical effects, of polymer dispersed liquid
crystals starting from the Monte Carlo configurations simulated for a lattice spin model. We consider droplets
with radial, bipolar, and random boundary conditions and examine to what extent their predicted deuterium
NMR spectra differ in the presence of molecular motion.
The NMR spectrum I(w) is calculated with a relaxation function formalism
where
In fig.1 we show an example of the effect of diffusion on the calculated spectra
