The relationship between the solid state structures and the electronic absorption properties in polysilanes is of widespread interest.

Variable temperature, high resolution, solid state sup 13 C NMR spectra are reported for semi-crystalline and amorphous poly(p-phenylene sulphide) (PPS), for the crystalline cyclic pentamer of PPS

Laser or electron beam annealing can be carried out with either pulsed or steady beams. The beams may be large or small, may persist for only nanoseconds or dwell on a spot for many milliseconds.

Nuclear magnetic ordering in solid sup (3)He provides the ultra- low temperature physicist with a unique opportunity to study cooperative magnetic in a quantum spin system.

Solid-state proton NMR with fast magic-angle sample spinning has been used to study the structure and dynamics of block and random ethylene oxide/propylene oxide copolymers in the bulk and as 30 wt

Poly(3,3-diethyloxetane) (PDEO) crystallizes in two different forms depending on the temperature of crystallization.

We show that solitarylike stimulated Raman excitations are possible in massive wavelength-division multiplexed fiber-optic systems.

In dense wavelength-division-multiplexed transmission with strong dispersion management, most pulses inevitably have many partial collisions with pulses of an interacting channel.

With computer simulation, we study soliton propagation in an all optical, long distance communications system where fiber loss is periodically compensated by Raman gain.

We report soliton self-frequency shift of over 20% of the optical frequency in a tapered air-silica microstructure fiber that exhibits a widely flattened large anomalous dispersion in the near infr
