Inhomogeneous dephasing time
WebbAn attenuated total reflectance infrared spectroelectrochemical (ATR-IR-SEC) technique has been developed that uses a surface-proximal doped Si ATR crystal as both the ATR optical element and the working electrode. This allows redox processes of monolayers of molecules attached to the Si surface to be probed through changes in their molecular … WebbDephasing is observed to be exponential in time, indicating the presence of a broadband noise source, rather than Gaussian, previously seen in systems with nuclear-spin …
