A simplified approach to quantum yield ([Formula: see text]) measurement using in situ LED NMR spectroscopy has been developed. The utility and performance of NMR actinometry has been demonstrated for the well-known chemical actinometers potassium ferrioxalate and o-nitrobenzaldehyde. A novel NMR-friendly actinometer, 2,4-dinitrobenzaldehyde, has been introduced for both 365 and 440 nm wavelengths. The method has been utilized successfully to measure the quantum yield of several recently published photochemical reactions.
