The first investigation of the phonon modes in binary InN was an extrapolation of the Gai-xInxN (0 < x < 1) alloy modes in reflection towards the binary compound [1], A typically high free carrier concentration in the mid 1020 cm 3 range controls the absorption (Drude absorption) in the infrared and must also account for the broadened Reststrahlen band in pure InN films (e.g. in [1]). In this case infrared active phonons couple to the plasma of the free electrons forming phonon-plasmon coupled modes [10,11], However, layers of low carrier concentration have been achieved and pure LO phonon energies have been derived in Raman spectroscopy. Resonant Raman spectroscopy at 514 nm has been performed, assigning five of the six Raman allowed zone centre phonon modes [8,9] (TABLE 1).

Valuable spectroscopic studies on the dithiolene chelated to Mo in various enzymes have been enhanced by the knowledge of the structure from X-ray diffraction. Plagued by interference of prosthetic groups—heme, flavin, iron-sulfur clusters—the majority of information has been gleaned from the DMSO reductase system. The spectroscopic tools of X-ray absorption spectroscopy (XAS), electronic ultraviolet/visible (UV/vis) spectroscopy, resonance Raman (RR), MCD, and various electron paramagnetic resonance techniques [EPR, electron spin echo envelope modulation (ESEEM), and electron nuclear double resonance (ENDOR)] have been particularly effective probes of the metal site. Of these, only MCD and RR have detected features attributable to the dithiolene unit. Selected results from a variety of studies are presented below, chosen because their focus is the Mo-dithiolene unit and organized according to method rather than to enzyme or type of active site.

Photoelectron spectra of Cd compounds have been reported see Photoelectron Spectroscopy of Transition Metal Systems), but discrepancies have been noted. X-ray photoelectron spectroscopy has been used in surface studies. Simmetry, bond length, and eqnUibrium constants see Equilibrium Constant) of Cd complexes have been determined through IR and Raman spectroscopy. Resonance Raman spectroscopy and Photoluminescence allow investigation of the optical properties of ultrathin CdS films. Electron diffraction studies have been reported. ... 

None directly the MHQ technique yields a frozen powder, which can be analyzed by various types of low-temperature spectroscopy like X-, Q-band EPR, UV-Visible spectroscopy, resonance Raman and potentially or in the near future by MCD, Mossbauer, ESEEM, ENDOR, EXAFS, W-, D-band EPR, MAS-NMR and FTIR spectroscopy.

In the terminology of spectroscopy, resonance is the condition in which the energy state of the incident radiation is identical with that of the absorbing atoms, molecules or other chemical entities. Resonance is applied in various types of instrumental analysis such as nuclear resonance absorption and nuclearmagneticresonance. See absorption spectroscopy.
