  • Descrição: A straightforward, albeit still unexploited, approach to access sharp principal value features of the chemical shift tensor in slightly off‐magic angle, slowly spinning powder solids is revisited. Its major advantages consist of (i) the direct visualization of axial or more general tensor/site symmetry, (ii) the absence of any rotor‐synchronized or amplitude‐matched radiofrequency pulse, and (iii) the use of routine single‐pulse or cross‐polarization acquisition modes upon modest spinning speeds on a standard cross‐polarization/magic‐angle spinning probe. The experiments and simulations show that the principal value features remain well resolved in an easily accessible range of chemical shift anisotropy/spinning frequency ratios and have fixed spectral positions at different spinning speeds. Several useful applications of this simple and robust approach can be envisaged in organic and inorganic solids. © 2004 Wiley Periodicals, Inc. Concepts Magn Reson Part A 22A: 106–112, 2004
