Figure 2.
(A) Close-ups of the “allowed” (left) and “forbidden” spectra for M318 and I168 showing the change in peak intensities with relaxation delay (T). The “forbidden” spectra have been contoured at a 3.8-fold lower level than the “allowed” spectra. The forbidden spectrum for T = 1 ms uses double the number of scans as the corresponding allowed spectrum. (B) The experimental intensity ratios corresponding to the spectra shown in (B) (solid circles, M318, black; I168, red) and the fits (solid lines) to Equation 2 are shown on the bottom panel.
