Displacive Phase Transformations

Solid State Phenomena, 2009
Shear deformation and shuffling of atomic planes are elementary mechanisms of collective atomic motion that take place during displacive phase transformations. General displacements of atomic planes are examined, i.e. -surface type calculations extensively used for the stacking faults and crystal dislocations are applied to single plane shuffling and ...

Inhomogeneous phase shifting: an algorithm for nonconstant phase displacements

Applied Optics, 2010
In this work, we have developed a different algorithm than the classical one on phase-shifting interferometry. These algorithms typically use constant or homogeneous phase displacements and they can be quite accurate and insensitive to detuning, taking appropriate weight factors in the formula to recover the wrapped phase.

Gas-phase nucleophilic displacement reactions

Journal of the American Chemical Society, 1977
AbstractDisplacement reactions of each of a variety of anionic nucleophiles reacting with each of a variety of neutrals have been studied by pulsed ion cyclotron resonance (ICR) spectroscopy. Rate constants for these reactions are interpreted in terms of a three‐step reaction sequence.

Displacive Phase Transitions in Malononitrile

The Journal of Chemical Physics, 1968
The crystallographic phases and phase transitions of molecular crystals of malononitrile were investigated using 14N pure nuclear quadrupole resonance. The resonance frequencies, linewidths, and spin–lattice relaxation times were measured using pulse techniques.
