Polaritions, surface

The chondrocytes of the intermediate zone are more spherical than, and differ from, the cells of the superficial layer, which show surface polaritity. Chondrons are found in the intermediate layer. They consist of chondrocytes, pericellular matrix, and pericellular capsule. In this zone, the chondrocytes do not form vertical columns as extensively as is observed in the deep zone. At high magnification the collagen fibrils have a beaded appearance, which may reflect the high level of PGs seen in this region.

The term includes the Raman polariTability tensor elements as well the IR-dipole transition moment The variable N refers to the number of resonant modes on the surface and iT specifies the damping constant or lifetime of the vibration. From Eq. (7.2), it is obvious that signal intensities increase as the term — ft>q) goes to zero as it approaches resonance. 

The surface potential at the interfacial layer is controlled by the surface excess of ions, their charges and polariTation, packing density, and dipole moment or induced dipole moment it can be determined by special techniques, that is, the vibrating plate method, combined with a Kelvin probe. Experimental data together with the most suitable prediction models may include the ion concentration in the bulk or ionic strength, and, when dealing with a monolayer, the ion number density in the monolayer, the monolayer thickness, and ion diameter. 

Furthermore, the coupling of the quasiparticle surface phonon with other quasiparticles such as Bloch electrons, magnons, plasmons, or polaritions are important ongoing research topics that lead in many cases beyond the well-established single-particle picture. Here, Section 8.2.5.2 could only give a small impression on phonon coupling issues.
