The dynamics of the crystal has been described in terms of phonon modes under the unit cell approximation. The translatory and libratory modes of different units of the crystal have been identified and assignments are made using far ir and Raman data on various isomorphous tutton salts.

The lattice vibrations of molecular crystals arise from the translational and rotational motions of the molecules, which are unhindered motions in the gas phase.
One of the first books devoted entirely to the subject of Raman microscopy, Raman Microscopy addresses issues of great interest to engineers working in Raman-microscope development and researchers concerned with areas ofapplication for this science. The book is written by several world recognized experts, who summarize the Raman effect before discussing the hardware and software involved in todays instruments. This format provides an excellent introduction to this up-and-coming discipline. All important applications, including those in materials science and earth science are covered in depth. Turrell, The Raman Effect.
The laser serves only in a secondary role for FT-IR spectroscopy, but as a source for excitation it has greatly revolutionized conventional Raman spectroscopy and led to the advent of new techniques including coherent anti-Stokes Raman scattering CARS , Raman gain, inverse or hyper- Raman spectroscopy. Both FT-IR and Raman techniques have also benefited from the improvements in optoelectronic and data processing systems. While a moving mirror with high mechanical precision and a high quality beam splitter are basic to an FT-IR instrument, a double monochromator with precision gratings, which may be holographic, and a laser as light source are intrinsic to a Raman spectrometer. Improved detector systems pyroelectric bolometers, such as triglycine sulfate, TGS, for FT-IR or photon counting for Raman , not available a decade ago now serve vital functions. Utilization of an on-line mini-computer is all but essential for practical FT-IR spectroscopy in order to facilitate the data handling and computation; it can also serve as a valuable accessory for the signal averaging and manipulation of Raman data.

Дэвид Беккер умрет. Халохот поднимался вверх с пистолетом в руке, прижимаясь вплотную к стене на тот случай, если Беккер попытается напасть на него сверху. Железные подсвечники, установленные на каждой площадке, стали бы хорошим оружием, если бы Беккер решил ими воспользоваться.
