Abstract New NQR methods, developed over the past years, are discussed: 1. Two frequency NQR double resonance, 2. the influence of strong off-resonance combination of rf pulses on demagnetized state in NQR, 3. remote NQR.

Abstract 17O nuclear quadrupole resonance spectra have been measured in an 17O enriched polycristalline sample of DL-proline with the help of 1H - 17O 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 sites. One set with the short proton-oxygen distances belongs to the C - O • • • H groups whereas the other with the long proton-oxygen distances to the C = O groups
