WebThe observation of diastereotopism led to the conclusion that 22 is chiral, at least on the NMR timescale. The origin of the chirality in 22 and its derivatives is best explained by slow inversion of the benzopentathiepin ring due to an exceptionally high barrier (ca. 29 kcal mol −1 ) to ring inversion, as has been noted for simple ...

WebOct 21, 2024 · The statement "chirality is the same thing as helicity for massless particles" is also meaningless. When people say this, they're trying to convey that a massless left/right-chiral field annihilates a left/right-helicity particle. But it also creates a particle of the opposite helicity. That's the origin of your second confusing statement ... how can i email dpd
