Research Interests:
Solid-State Nuclear Magnetic Resonance (NMR), and complimentary techniques such as X-ray crystallography, X-ray powder diffraction and ab initio calculations are to be applied for the characterization of anisotropic NMR interactions, dynamic motion and chemical and structural properties of a variety of chemical substances and inorganic materials. Our current research focuses are NMR of quadrupolar nuclei in main group and transition metal metallocenes and related organometallic complexes, theoretical determination of electric field gradients in solid vanadates and niobates and fast MAS and wideline static NMR of niobate-based materials.
Experimental (A) and simulated (B) 27Al SATRAS NMR spectra of Cp*2Al+, the (bis(pentamethylcyclopentadienyl) aluminum cation
We are also interested in solid-state NMR studies of insensitive quadrupolar nuclei with low magnetogyric ratios and/or natural abundances, as well as quadrupolar nuclei with nuclear electric quadrupolar moments that cause NMR spectra to be broadened beyond the limits of currently detectable bandwiths. We use a variety of special NMR pulse sequences to acquire useful NMR spectra of such systems, with much focus on the recently published QCPMG (quadrupolar Carr-Purcell Meiboom-Gill) spin echo NMR pulse sequences.. We are designing experiments which will make nuclei such as 25Mg, 39K, 49Ti, 91Zr and 93Nb more accessible for solid-state NMR experiments at standard magnetic field strengths.
A comparison of 91Zr NMR spectra of Cp2ZrCl2: Conventional 91Zr spin echo spectra and corresponding 91Zr QCPMG spectra.
