CO specpure from either Matheson or Praxair was used as a molecular probe in order to assess the Lewis acidic properties of coordinatively unsaturated (cus) cations either located in the dehydrated zeolite nanocavities as charge-balancing cations, or exposed at the dehydrated surface of oxidic materials. CO is capable of interacting with the cus cations leading to the formation of adducts of different stability according to the chemical nature of the cation. Weak electrostatic adducts are formed on alkaline metal cations, u-coordinated species of intermediate stability on non d/d metal cations, whereas high-stability carbonyl-like species originated by a a-coordination -l-7r-back donation of d electrons are formed on d block metal cations.

Note that this condition is automatically satisfied for three-dimensional systems, where there is no non-leading u-coordinates. In this case the global map assumes the form... [Pg.371]

To illustrate the essential ideas, we consider a raonoatomic linear chain with BC s midway between the ions (Fig.4.16) [4.17]. We introduce a short-range ion-BC force constant f and a force constant f which describes the coupling between nearest BC s. For the sake of simplicity, the short-range interaction between neighbouring ions as well as the Coulomb interactions are neglected. The equations of motion are (u coordinates of the ions, v coordinates of the BC s)... [Pg.131]
