High fidelity is typically measured by evaluating the yield and selectivity of the catalytic reaction. Analytical techniques such as gas chromatography (GC), high-performance liquid chromatography (HPLC), and nuclear magnetic resonance (NMR) spectroscopy are commonly used to quantify the products and by-products of the reaction. The fidelity can also be assessed by studying the catalyst's behavior under different reaction conditions and with various substrates.
