Coupled techniques are vital because they offer several advantages over standalone methods:
1. Enhanced Sensitivity: By combining techniques, researchers can detect species and phenomena that might be missed using a single method. 2. Complementary Information: Different methods can provide complementary data, such as structural, chemical, and kinetic information. 3. Real-time Analysis: Coupled techniques often enable real-time monitoring of catalytic reactions, allowing for the observation of transient states and intermediates.
