Chemical Shift Anisotropy (CSA) refers to the dependence of the chemical shift on the orientation of a molecule in an external magnetic field. In the context of catalysis, CSA plays a crucial role in understanding the interaction between catalysts and substrates, as well as providing insights into the structure, dynamics, and electronic environments of catalytic systems. CSA is particularly relevant in NMR spectroscopy, where it can significantly impact the observed chemical shifts of nuclei.
