This technique can be used in tandem with a type of Overhauser effect analysis to distinguish between molecular conformations.
This technique can be used in tandem with a type of Overhauser effect analysis to distinguish between molecular conformations. Materials whose conduction electrons acquire ordered spins during this technique exhibit the Knight shift. A quadratic equation in cosine phi describes the relationship between dihedral torsion angle and a quantity fundamental to this technique in an equation named for Karplus. That quantity controls the shape of signals formed in this technique, which frequently form doublets and triplets. For 10 points, name this form of molecular analysis, which may be carried out on any atom with an odd mass number, most prominently with carbon-13 and hydrogen.
