Highlights with ‘Relativistic DFT’

Spin Orbit Coupling in Charge Transfer States

Researchers from the University of Amsterdam investigated the effects of twisting an electron donor-acceptor molecule. The conformational dependence of the matrix element for spin–orbit coupling (SOCME) and of the electronic coupling for charge separation are...

Density Functional Theory Study on the Catalytic Dehydrogenation of Methane on MoO3 (010) Surface

With the fluctuations in oil and gas prices, and the consequences of the COVID-19 outbreak, there is an even stronger increasing interest in transforming natural gas into value-added chemicals that have higher economical and strategic...

Benchmark Study on the Calculation of 119Sn NMR Chemical Shifts

Nuclear magnetic resonance (NMR) spectroscopy is one of the most important analytical methods for elucidating chemical structures. Nevertheless, for some nuclei the range of possible chemical shifts is huge and corresponding NMR measurements are often...

Fast Intrinsic Emission Quenching in Cs4PbBr6 Nanocrystals

Cs4PbBr6  belongs to the family of 0D metal halides, with separated and isolated [PbBr6]4- octahedra. These systems, in both nanocrystal and bulk forms, have been reported as being either non-emissive or green-emissive at room temperature...

Exceptional Uranium-Nitride Triple Bond Covalency confirmed with NMR

The Liddle group continues to deeply probe the unusual nature of the actinide-main group bonds through combined experimental and computational studies. We previously highlighted the first U-N triple bonds along with a number of other...

Transformable Polyoxometalates, Sustainable Nanoelectronics

Molecular metal oxides, or more notably polyoxometalates (POMs) are being researched for over a century. Their structure benefits from very high stability, whose inherent connectivity relies predominantly on metal-oxygen bonds. Theoretical insights into the bonding...

Aqueous speciation of polyoxometalates

Polyoxometalates self-assembly in aqueous solution is still a subject under study. This is due to the high complexity that involves describing all the chemical equilibria. Experimental techniques investigated this matter with great successes yet more...

Investigating the mechanisms for methylmercury poisoning

Methylmercury is an electrophilic toxicant present in the list of the ten most chemicals of major public health concern substances provided by the WHO. Its capacity of binding to biologically relevant thiols and selenols, disrupting...

Strong covalent Th-Th bond inside C80

An unprecedented thorium-thorium bond has been characterized inside the icosahedral Ih(7)-C80 carbon cage. The single-crystal X-ray diffraction of Th2@Ih(7)-C80 unambiguously determined that the two encapsulated Th atoms are separated by 3.816 Å, accurately reproduced by DFT...

Is Metallophilicity Really Attractive?

Metallophilicity (M-M’ closed-shell interaction) was discovered in the early 1970s, when close metal-metal contacts were observed extensively in d10-d10 (AuI-AuI, AgI-AgI, CuI-CuI, Pd0-Pd0, Pt0-Pt0) and d8-d8 (RhI-RhI, IrI-IrI, PtII-PtII, PdII-PdII) transition metal complexes. Metallophilicity is...
