HSQC is often used in conjunction with other analytical techniques to provide a comprehensive understanding of catalytic systems. For example: 1. Combining with Mass Spectrometry (MS): This can help in identifying the molecular weight and composition of intermediates and products. 2. X-ray Crystallography: When used alongside HSQC, it can provide detailed three-dimensional structures of catalysts and substrates. 3. Computational Chemistry: HSQC data can be used to validate computational models of catalytic mechanisms, providing a more complete picture of the catalytic process.
