PHOTOFRAGMENTATION-LASER-INDUCED FLUORESCENCE FOR DETECTION OF NITRIC OXIDE-BEARING EXPLOSIVES

A method for identifying a presence of a nitro (NO)-bearing compound suspected of being included in a sample includes photodissociating a sample into one or more fragments that include a NO molecule, where the NO molecule has an electron in a first-vibrational excited state of an electronic ground s...

Zusammenfassung:	A method for identifying a presence of a nitro (NO)-bearing compound suspected of being included in a sample includes photodissociating a sample into one or more fragments that include a NO molecule, where the NO molecule has an electron in a first-vibrational excited state of an electronic ground state. Laser-induced fluorescence (LIF) is applied including directing UV light from a UV laser source at the sample to induce fluorescent light. An emission wavelength of 270 nm to 274 nm from fluorescent light received is used to identify a presence of the NO-bearing compound in the sample.
