-
Even though the protons give a doublet the coalescence temperature can be established because of the large difference in chemical shift values.

For conformational stability of bridged biphenyls at ambient temperatures, energy barriers of about 80 kJ/mol are necessary, see C. Jaime, J. Font, J. Org. Chem. 55, 2637 (1990).
