The AA′BB′ system of conformational populations for derivatives of choline, tryptamine and tyramine

Abstract

Equations relating the magnetic resonance spectral parameters N and L of the AA'BB' system to the conformational populations of 1,2-disubstituted ethanes of the type XCH₂CH₂Y are derived for a variety of substituents. These equations are used to obtain conformational information for choline, tryptamine and tyrarnine derivatives in solution.
