Splitting it up : Excellent agreement between the experimental and the quantum‐chemically simulated Raman optical activity (ROA) spectrum of (+)‐poly(trityl methacrylate) shows that the polymer backbone adopts a left‐handed helical conformation while the trityl side groups display a left‐handed propeller conformation. Thus ROA can be used to determine the complete structure of synthetic chiral polymers in solution.
