The structures of various (084) and ( 83) complexes have been determined (Tables I and III). The vibrational infrared, NMR, and electronic spectra of the Mo-trithio- and perthiocarbonate complexes have been compiled in Table XIII. The energy of the C=8 vibration of the coordinated ( 83) " ligands invariably is lower ( 980 cm ) than that of the C=8 vibration in the ( 84) complexes ( 1050 cm ) and can be used as a spectroscopic diagnostic criterion for the identification of the ligands with considerable confidence. An additional diagnostic indicator for the ( 83) and ( 84) ligands is the...

The Gibbs free energies are calculated using standard thermodynamic tables which are easily usable by machine since they give the data in the form of polynomial coefficients. The data are sometimes limited to 6000 K and it is therefore necessary to make extrapolations or to carry out calculations of partition functions from spectroscopic data In the latter case, which is certainly more reliable, one can determine standard thermodynamic functions with the aid of the classical formulae of statistical thermodynamics. The results may then be fitted to polynomials so that they match the tabulated data . Furthermore the calculation of partition functions is necessary for spectroscopic diagnostics and for the calculations of reaction rate parameters. 

For spectroscopic diagnostics one must realize that the lines ouM have a hi intensity compared to the continuum, they must be well separat L und at atmosjA ric pressure, an Abel s inversion is nerally needed. 

AlN(g) is lightly favoured and we have consequently a low AlN(g) molar fraction. Since aluminium has quite a low ionization potential, the ionization of aluminium begins at low temperatures (this is an important point for spectroscopic diagnostics). 

The third group of techniques consists of reacting a chloride with the nitrogen-hydrogen or ammonia plasma, as also used in cla ical synthesis. It has been originally tested in plasma torches dealing only with gas phase reactions, followed by condensation. We believe that this is probably the most reliable method for spectroscopic diagnostics of gas phase reactions. Exell et al. have obtained very fine amorphous...

A spectroscopic diagnostic has been developed to maintain the optimum conditions of ICP operation, in particular the flow rates of the aerosol carrier. The ratio between an atomic line of copper and an ion line of manganese is used to adjust divergent intensity responses because of unfavorable operating conditions. When this diagnostic is applied, the variability of the interference coefficients is small. The larger the correction factor, the larger the error in the quantitation of the analyte line subject to interference. 

Four-wave mixing is of Importance both fundamentally and for spectroscopic diagnostics. Extensive perturbational investigations of the process have been done both directly and diagramatically. >3 Exact solutions for various particular physical processes have been previously obtained.In this paper, we develop a technique for the semlclasslcal exact solution of a four-wave mixing process. For the sake of brevity, we will specialize to the dominant path, but the technique is applicable to other paths as well.
