Figure 7

Sum combination line region of the cosine FT spectra of the two-pulse W- and integrated four-pulse Ka-band ESEEM68, 69 (traces 1 and 2, respectively) obtained at gx. The quadrupole splittings, ΔνQ, are indicated for each trace. Experimental conditions for trace 1: mw frequency = 94.897 GHz; Bo = 3472.9 mT; mw pulses, 2×25 ns; temperature= 21 K. Experimental conditions for trace 2: mw frequency = 29.523 GHz; Bo = 1081 mT; mw pulses, 4×15 ns; temperature = 21 K. A frequency of zero is defined as double the 17O Zeeman frequency at the given magnetic fields.
