It is shown how amplitude-modulated radio-frequency pulses optimized for selective inversion of magnetization can be applied to static powder samples with inhomogeneously broadened spectra. Selective one-dimensional methods can in principle provide informa ...
A novel anal. technique, Fourier-transform IR photopyroelec. spectroscopy (FT-IR-P2ES) is demonstrated and applied to spectroscopic investigations of solid materials. The salient features of the technique and its advantages over other conventional FT-IR ph ...
The variable-speed magic-angle sample spinning (VSMAS) technique was extended to two-dimensional spectroscopy in solids yielding two-dimensional spectra free of spinning sidebands. [on SciFinder (R)] ...
The performance of deuterium-carbon correlation (DECOR) spectroscopy for the assignment and measurement of deuterium quadrupolar couplings in fully deuterated liquid crystalline phases is analyzed. The experiment relies on a broadband polarization transfer ...
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 ...
A method is proposed for the sepn. of overlapping multiplets or substructure within multiplets in two-dimensional spectra. The issue of the recognition and measurement of homonuclear couplings in arbitrary mols. was discussed. The overlapping cross-peak mu ...
Two-dimensional Fourier transform (2D FT) spectroscopy was applied to ion-cyclotron resonance (ICR) to obtain direct evidence for mass transfer due to ion-mol. collisions. The 2D FT ICR expt., which is closely analogous to 2D exchange NMR spectroscopy (NOE ...
A simple variation of double-quantum spectroscopy is described where the transfer of double- into single-quantum coherence is carried out by means of 2 pulses with small flip angles via eigenstate populations and zero-quantum coherences. For systems with 4 ...
Attention is drawn to a class of signals that appear if the rotation angles of the radio-frequency pulses in the 2-dimensional (2D) exchange expt. are inadvertently or deliberately set to b!=p/2. The signals (zz signals) arise from longitudinal 2-spin orde ...
A novel type of difference spectroscopy is proposed to improve two-dimensional exchange spectroscopy by reducing diagonal peaks which are often dominant in complex cases such as in 2-dimensional nuclear Overhauser effect spectra of biopolymers. The diagona ...
