The possibility of combination transitions in NQR
We examine the possibility of detecting, NQR transitions in the presence of dipole-dipole or indirect spin-spin coupling of two quadrupolar nuclei at frequencies that are multiples of the quadrupole frequency of either nucleus and at combination frequencies, in particular at summation and difference frequencies, which can be detected by double quadrupole resonance.
