Infrared Multiphoton Dissociation

Infrared multiphoton dissociation (IRMPD) is a powerful mass spectrometry technique used to identify the structure of gas-phase molecules. IRMPD relies on the absorption of multiple photons of infrared radiation to break chemical bonds and fragment the molecules, producing ions that can then be detected and characterized by mass spectrometry. By directly analyzing the product ions of a sample, IRMPD can provide valuable information about the structures of complex molecules without the need for prior knowledge or chromatographic separation. IRMPD is used in a variety of scientific fields, including pharmaceuticals, biochemistry, and analytics.
