“…145,146 Raman spectroscopy can also be used in a time-resolved manner to track the structural changes under in situ conditions. 147 In particular, Raman has been useful in identifying structures, vibrational modes and molecular conformations, as well as bond orientations of organophosphorus compounds in their pure form or when adsorbed onto surfaces. 148−152 Depending on the excitation energies, laser power, signal-to-noise ratio, and integration time, many fingerprint regions could be distinguished.…”

“…A typical Raman active vibrational mode of a molecule occurs in the 30–3200 cm –1 interval. Raman spectroscopy has been particularly used in determining the lattice dynamics and crystallinity of several materials, such as carbon-based, , metal oxides, , and polymers. , Raman spectroscopy can also be used in a time-resolved manner to track the structural changes under in situ conditions . In particular, Raman has been useful in identifying structures, vibrational modes and molecular conformations, as well as bond orientations of organophosphorus compounds in their pure form or when adsorbed onto surfaces. − Depending on the excitation energies, laser power, signal-to-noise ratio, and integration time, many fingerprint regions could be distinguished. , For example, Choi et al showed, using principal component analysis applied to Raman spectra, that nerve agents with similar molecular structures can be easily distinguished .…”

This Review summarizes the recent progress made in the field of chemical threat reduction by utilizing new in situ analytical techniques and combinations thereof to study multifunctional materials designed for capture and decomposition of nerve gases and their simulants. The emphasis is on the use of in situ experiments that simulate realistic operating conditions (solid–gas interface, ambient pressures and temperatures, time-resolved measurements) and advanced synchrotron methods, such as in situ X-ray absorption and scattering methods, a combination thereof with other complementary measurements (e.g., XPS, Raman, DRIFTS, NMR), and theoretical modeling. The examples presented in this Review range from studies of the adsorption and decomposition of nerve agents and their simulants on Zr-based metal organic frameworks to Nb and Zr-based polyoxometalates and metal (hydro)oxide materials. The approaches employed in these studies ultimately demonstrate how advanced synchrotron-based in situ X-ray absorption spectroscopy and diffraction can be exploited to develop an atomic- level understanding of interfacial binding and reaction of chemical warfare agents, which impacts the development of novel filtration media and other protective materials.
