molecular orientation

The first step provides for maximum molecular orientation in the machine direction.

Some implications of the equations are discussed, particularly as they apply to molecular orientation.

Figure 4 shows a typical experimental geometry for molecular orientation experiments.

In both black films, there is no sign of molecular orientation or rigidified structure of water.

The molecular orientation of the pyrazinium cation is dependent on the electrode potential.

The end-result is a fiber with a high degree of molecular orientation, and therefore exceptional tensile strength.

It has six faces, and by resting the cube on each of them in turn, a series of new molecular orientations might be induced.

The spectral information arising from this analysis gives insight into molecular orientation and vibrational symmetry.

The molecular orientation can differ from the laboratory axis in three directions, corresponding to three angles.

Another important consequence of the molecular orientation is that it induces the formation of many crystal nuclei.

There is only one molecular orientation for the normal HDPE films.

It depends on molecular orientation.

Key words: dipalmitoylphosphatidylcholine, Langmuir–Blodgett film, molecular orientation, infrared reflection–absorption spectra, surface pressure–area isotherm.

Only when proteins and polypeptides had a net positive charge was a marked effect noted on molecular orientation within brain lipid films.

Key words: polymer-dispersed liquid crystals, molecular orientation, infrared dichroism, electrooptical materials.

A second spiral cutting step will shift the molecular orientation from the machine direction into a direction under an angle of 45 .

To determine molecular orientation, the second-order hyperpolarizability tensor β, must be calculated.

The molecular orientation can be effectively correlated with the topography of the sample when atomic force microscopy experiments are conducted on the same object.

The molecular orientation is generally expressed by an "order parameter," which depends on both the angular position and the shape of the orientation distribution.

Molecular orientation can be probed by observing the polarization of the second harmonic signal, generated from a polarized beam.

The heat setting step prevents the film from shrinking back to its original unstretched shape and locks in the molecular orientation in the film plane.

As molecular layers adsorb to surfaces it is often useful to know the molecular orientation of the adsorbed molecules.

These four terms give rise to the second harmonic signal, and allow for calculation of material properties such as electronic structure, atomic organization, and molecular orientation.

Molecular orientation in the LB films was quantitatively evaluated by a method recently proposed by Umemura et al.

Light-induced molecular orientation switching and large intrinsichysteresis in a homeotropic cell of nematic liquid crystals areobtained.
