Lithium intercalation complexes of layered transition metal dichalcogenides: An NMR survey of physical properties

NMR studies of lithium intercalation complexes of layered disulfides and diselenides of Group IVb and Vb transition metals establish that the inclusion of a guest lithium atom between the host dichalcogenide layers is accompanied by the donation of approximately one electron to the host. Measurements of the electrostatic and magnetic interactions between the lithium atom and the host and the rate of lithium atom motion are discussed.
