[18]-Annulene shows two signals in its 1H NMR spectrum:
Chapter 15, Problem 15P(choose chapter or problem)
\(\text { [18] }\)-Annulene shows two signals in its \({ }^{1} H\ N M R\) spectrum: one at \(9.25 \mathrm{ppm}\) and the other to the right of the TMS signal at \(-2.88 \mathrm{ppm}\). What hydrogens are responsible for each of the signals? (Hint: Look at the direction of the induced magnetic field outside and inside the benzene ring
in Figure \(15.6\) .)
