Selective Inversion of Spin-Tickling Spectra in a ^<13>C-^1H Spin System

Selective spin inversion usually produces transfer of the longitudinal magnetization in a coupled spin system. Under irradiation of a stirring-field, however, transverse ones and multiple quantum coherences can also be simultaneously transferred in this process. For a coupled ^<13>C-^1H spin system under irradiation resonant with one of the ^1H lines, ^<13>C tickling spectra are observed immediately after inversion of one component of the ^<13>C-polarizations. Spectra thus obtained are considerably different from a simple selectively-inverted pattern of the steady-state ones. These changes depend on amplitude and frequency of the rf field, frequency and phase of the inversion pulse and inhomogeneity of the static magnetic field. The most prominent change in these spectra can be explained by transfer of zero quantum coherence, which is made in the differential form into each line of the spectra.
