Dislocation dynamics in a Ni-3(Al, Ta) single-crystal alloy have been studied by means of mechanical spectroscopy at intermediate temperatures, that is in the temperature range of the flow stress anomaly. The mechanical loss of specimens predeformed at 300 ...
NMR spectroscopy is one of the newer spectroscopic techniques for investigating the static, dynamic and electronic structures of molecules adsorbed onto metal catalyst surfaces. We review recent progress in the application of solid-state NMR methods to the ...
The intramol. energy relaxation processes of UV-excited C60 mols. embedded in Ar crystals were studied by picosecond fluorescence studies and femtosecond pump-probe absorption spectroscopy. The various internal energy relaxation steps are clearly identifie ...
Several methods for obtaining selective correlation spectra are described where the relative signs of multiplet components can be manipulated virtually at will. These methods yield spectra with very high resoln. that can be recorded in a short exptl. time. ...
A technique is proposed which simplifies the study of spin-lattice relaxation in multilevel nuclear spin systems. The introduction of non-participating "spy" nuclei, which interact with the nuclei under investigation through scalar or dipolar coupling, m ...
Spurious responses, known as phantom and ghost responses, in NMR 2-dimensional J spectroscopy, can be removed by a 4-step sequence where the phase of the C refocusing pulse is cycled through O, 90, 180, 270 Deg while the receiver ref. phase is alternated. ...
