Chirality - determination of optical activity
WebJan 10, 2024 · 1. "optical activity" is a problematic term if only because it implies EM radiation in the visible range. Unfortunately there isn't a simple general term. Though you could say, "can chiral macroscopic objects rotate the plane of EM waves of a suitable wavelength?" – matt_black. WebFeb 23, 2010 · Since the chirality induction mechanisms in 1, 2, and 3 are essentially similar, despite the difference in host-guest binding, the chiroptical outcome and especially the sign of induced chirality are the same, hence allowing facile and straightforward determination of the absolute configuration of various chiral compounds on the basis of ...
