Multimodal spectroscopy

Definition

Multimodal spectroscopy refers to the use of multiple spectroscopic techniques simultaneously or in a complementary manner to obtain a more comprehensive understanding of a sample's properties. This approach enhances the detection capabilities and provides richer data, enabling researchers to analyze various aspects of the sample, such as its molecular composition, structure, and interactions. By combining methods like absorption spectroscopy with others, scientists can improve sensitivity and specificity in their analyses.
