Oral presentation

Structural analysis of Cs adsorption on Cs-montmorillonite using ab initio calculation and $$^{133}$$Cs solid state NMR, 1; GIPAW prediction of $$^{133}$$Cs NMR parameters

no journal, , 

The structures of Cs adsorption on montmorillonite were investigated by the nuclear magnetic resonance (NMR) spectroscopy. NMR parameters were evaluated by the first principle calculations using GIPAW method in order to identify the relationship between adsorbed Cs structures and NMR parameters. It was confirmed that the chemical shift for Cs adsorbed on Al site in tetrahedral sheet was shifted to low magnetic field.

Structural analysis of Cs adsorption on Cs-montmorillonite using ab initio calculation and $$^{133}$$Cs solid state NMR, 2; $$^{133}$$Cs MAS and 3Q MAS NMR

Okamoto, Takuya*; Okubo, Takahiro*; Iwadate, Yasuhiko*; Deguchi, Kenzo*; Shimizu, Tadashi*; Oki, Shinobu*; Tachi, Yukio

no journal, , 

The structures of Cs adsorption on montmorillonite were investigated by the nuclear magnetic resonance (NMR) spectroscopy. The NMR spectra of Cs adsorbed montmorillonite samples with different Cs contents were collected by $$^{133}$$Cs Magic Angle Spinning (MAS) NMR and $$^{133}$$Cs Triple Quantum (3Q) MAS NMR. The adsorbed Cs structures were evaluated based on the correlations between the structural characteristics and the values of the NMR parameters predicted by the first principal calculations.

Structure of hydrated Cs on montmorillonite

Okamoto, Takuya*; Okubo, Takahiro*; Iwadate, Yasuhiko*; Deguchi, Kenzo*; Shimizu, Tadashi*; Oki, Shinobu*; Tachi, Yukio

no journal, , 

The structures of Cs adsorbed on montmorillonite were investigated by $$^{133}$$Cs Magic Angle Spinning (MAS) NMR spectroscopy. The NMR spectra of Cs adsorbed on montmorillonite samples were measured under different relative humidity levels and were analyzed to evaluate the change in the structure of hydrated Cs sorbed on montmorillonite.
