Optical rotation (OR) measurements are a common method to characterize chiral systems, but it has proven challenging to establish a chemically intuitive connection between the structure of a molecule and the OR direction or magnitude it induces. With the advent of quantum mechanical simulations of OR, significant efforts have been made to clarify this structure-property relationship. One avenue of research has focused on developing methods to decompose the OR into contributions from functional groups, bonds, or even individual atoms within the molecule 1-6 .
