Effects of the two tunneling motions ΔE are plotted in MHz as a function of J for several K_a-values and for all three tunneling sublevels. In identifies the level arising from the In conformation. + and − identify the tunneling sublevels arising from the Out conformation. The effects of the tunneling motion connecting the In and Out conformations can be seen for the 17_8, 9 In and 17_7, 10 − sublevels.
