How exactly are these two isomers structurally any different? Vokesk (talk) 20:30, 22 June 2013 (UTC)[reply]

That's the whole point of atropisomers. In theory, they're just different conformers of the same molecule, but the substituents are so large that in practice, steric hindrance inhibits rotation about the axis, and thence conformational interconversion is likewise blocked. Thus the conformers can be isolated. DS (talk) 13:47, 15 July 2013 (UTC)[reply]
