Highlights with ‘spectroscopy’

Improved absolute configuration determination of complex molecules with VCD

All biological systems are three-dimensional and determining the exact configuration of the system is important for pharmaceutical applications and drug design. However, determining 3D-structures is complicated and difficult. Vibrational circular dichroism is a method using...

Fast & efficient plasmonic excitations in metallic nanoparticles

The great potential of employing tight-binding approximations after a regular DFT ground state calculation has been demonstrated in a recent paper. With the TD-DFT+TB approach (see thesis by Robert Rüger), plasmon resonances in large silver, gold,...

Unraveling structure and reactivity of Pt complexes: NMR & EPR

A recent combined experimental and theoretical study by the Kaupp group scrutinizes transition metal phosphanide chemistry which helps to understand catalytic processes involved in C-P bond formation and breaking. The reaction of a Pt-PPh3 with...

SCM at Physics@Veldhoven

Going to the Physics@Veldhoven meeting? Don’t miss the SCM table at the “sponsorplein” (Meijerij Foyer) or make a speed date appointment (Limburg Foyer) for Wednesday 22nd! Stan and Mirko would love to discuss how the Amsterdam...

Plasmon Enhanced Two Photon Absorption: Paper & Tutorial

The DIM/QM method for modeling plasmon-enhanced photochemical properties has recently been extended to several non-linear optical properties with damped cubic response theory. A recent paper by Zhongwei Hu and Lasse Jensen discusses the methods to...

Chiroptical activity of bisphosphine-stabilized gold clusters studied with ADF

By running DFT and TDDFT calculations with ADF, Natalia V. Karimova and Christine M. Aikens could gain detailed insight into the origin of chiroptical activity and the effects of ligands in bisphosphine-stabilized gold clusters [Au11X4Cl2]+ and [Au8X3(PPh3)2]2+ (X...

SO-HALA NMR Chemical Shifts: General Trends Across the Periodic Table Explained with ADF

In a recently published JCTC article Jan Vicha and coworkers explain the SO-HALA (Spin-Orbit Heavy Atom on the Light Atom) NMR chemical shifts across the periodic table based on relativistic DFT calculations with spin-orbit coupling ZORA...

New NMR tutorial

Check out our new GUI tutorial on NMR chemical shifts and spin-spin coupling constants! Splittings due to the spin-spin couplings can now be displayed and regions of chemical equivalency, e.g. as in freely rotating methyl groups,...

Surface-enhanced Raman optical activity

Raman optical activity has proven to be a powerful tool for probing the geometry of small organic and biomolecules, but the fledgling technique of surface-enhanced Raman optical activity (SEROA) remains an experimental challenge. SEROA of...

Spin-orbit coupling increases dye-sensitized solar cells efficiency

The incident photon-to-current-conversion efficiency (IPCE) of dye-sensitized solar cells depends, amongst others, on the light-harvesting capabilities of the dye. In two recent studies, researchers from the Computational Lab for Hybrid/Organic Photovoltaics of CNR-ISTM Perugia, Italy,...
