Photon correlation technique

These observations indicate a decreased hydration interaction between water and the ammonium ion (or its derivatives) as compared to the sodium ion. The findings are confirmed by unpublished data131 regarding AOT micelles in isooctane saturated with D20. The smallest aggregates (micelles) observed with the photon correlation technique are smaller which would follow from the fact67 that the heats of ionic hydration are smaller and the hydrogen bonds (OD. .. X) to a foreign acceptor (X) are weaker in D20 compared to H20. 

To obtain information on a single particle is important for studying the dynamic properties of living cells. Tishler and Carlson used a DLS microscope spectrometer to study the dynamics of the plasma membrane of individual human red blood cells. They combined an inverted microscope with the photon correlation technique [55,56]. The scattering volume of an 8 /mi diameter cross section and the spread in scattering angle of 5.5r enabled them to study the correlation time due to the spontaneous fluctuations of cells. The detected fluctuation...

The study of optical lattices has been extended from ID to 2D and 3D using the phase-insensitive configurations mentioned above, and also by stabilization of the relative phases of the beams [30]. The spectra of such lattices has been studied by both absorption and emission techniques [24, 31, 32, 33, 34], as well as by photon correlation techniques [35, 36]. There have also been studies of lattices tuned far from resonance, using non-spectroscopic methods [37, 38]. ... 

The techniques described under Photon Correlation exploit the correlation between the photons emitted by single molecules and by a small number of molecules. Picosecond photon correlation techniques investigate effects driven by the absorption of a single photon of the excitation light. The effects investigated by FCS are driven by Brownian motion, rotation, diffusion effects, intersystem crossing, or conformational changes. Because of these random and essentially sample-internal stimulation mechanisms, correlation techniques do not necessarily depend on a pulsed laser. 

The translational diffusion coefficient D is obtained from the first cumulant T of the electric field time correlation function (t), which is directly measured by photon correlation technique...

As mentioned in the introduction to Parts A and B, new experimental methods have enriched and advanced the field of atomic spectroscopy to such a degree that it serves not only as a source of atomic structure data but also as a test ground for fundamental atomic theories based upon the framework of quantum mechanics and quantum electrodynamics. However, modem laser and photon correlation techniques have also been applied successfully to probe beyond the traditional quantum mechanical and quantum electrodynamical theories into nuclear stracture theories, electro-weak theories, and the growing field of local realistic theories versus quantum theories.

The chosen form relates to the previous Eq. (A. 12) and expands it by an inclusion of the time dependence. 5(q, t) expresses the correlation in time of the scattering amplitudes measured at two times separated by t. The stationary character of thermal equilibrium states implies that the right-hand side is independent of In dynamic light scattering experiments the determination of S q,t) is accomplished by the photon correlation technique. In dynamic neutron scattering experiments, spin-echo measurement can be used in order to obtain the correlation function.
