1 7 0 nuclear quadrupole resonance spectra have been measured in an l v O enriched polycristalline sample of DL-proline with the help of 1 H l v O nuclear quadrupole double resonance technique. The results show the presence of eight chemically inequivalent oxygen sites corresponding to four inequivalent proline molecules in the unit cell. The oxygen sites may be grouped into two sets of four si...

In this context a "dimension" can be of a spatial or of a spectroscopic nature. In the last two decades, multidimensional nuclear magnetic resonance and imaging have proven to be most useful tools for the investigation of materials. It turned out that some of these measuring principles can be applied to zero-field N Q R as well. The purpose of this presentation is to elucidate twodimensional ex...

H = S v i S v i + 1 ) y y corresponds to what is called the XY chain. The hexagonal compound PrCl3 provides a good approximation to the 1-D XY chain. The structure of PrCl3 is illustrated in Figure 1. Nearest neighbor Pr ions form chains along the hexagonal axis. Each Pr ion has nine close Cl neighbors which form three equilateral triangles; one triangle lies in the plane perpendicular to the h...

The molecular beam electric resonance technique has been used to examine the hyperfine spectrum of RbF. The Rb nuclear electric quadrupole interaction, the spin-rotation interactions, and tensor and scalar spin-spin interactions have been measured for both Rb isotopes, including their dependence on vibrational and rotational states. Transition frequencies have been determined to a precision of ...

Time-domain zero-field NQR methods are used to determine quadrupole coupling constants and asymmetry parameters for a variety of polycrystalhne solids. Results for aliphatic and aromatic groups are reported. Several cases are presented in which sites with small differences in quadrupole coupling constants are resolved, and very smah (CO. 1) asymmetry parameters are measured. Structure in the ze...
