The inverse-trans-influence in tetravalent lanthanide and actinide bis(carbene) complexes (2017)
Journal Article

© The Author(s) 2017. Across the periodic table the trans-influence operates, whereby tightly bonded ligands selectively lengthen mutually trans metal-ligand bonds. Conversely, in high oxidation state actinide complexes the inverse-trans-influence op... Read More about The inverse-trans-influence in tetravalent lanthanide and actinide bis(carbene) complexes.

Dynamic nuclear polarisation by thermal mixing: quantum theory and macroscopic simulations (2016)
Journal Article

A theory of dynamic nuclear polarisation (DNP) by thermal mixing is suggested based on purely quantum considerations. A minimal 6-level microscopic model is developed to test the theory and link it to the well known thermodynamic model. Optimal condi...
