Tuning the Thermal Stability and Photoisomerization of Azoheteroarenes through Macrocycle Strain**

Anne-Clémence Corminboeuf, Alan Scheidegger, Sergio Vela Llausi, Raimon Fabregat I De Aguilar-Amat

Azobenzene and its derivatives are one of the most widespread molecular scaffolds used in a range of modern applications, as well as in fundamental research. After photoexcitation, azo-based photoswitches revert back to the most stable isomer on a timescal ...

Capturing Non-local Effects in Kohn-Sham Density Functional Theory : Dispersion and Charge Transfer Phenomena

Andrey Laktionov

Density Functional Theory (DFT) and its time-dependent extension (TDDFT) have become two of the most popular approaches for computer simulations of the electronic structure and response properties of quantum systems. A reasonable compromise between accurac ...

Uniform broadband excitation of crystallites in rotating solids using interleaved sequences of delays alternating with nutation

Geoffrey Bodenhausen, Simone Ulzega, Marc Anthony Caporini

In solids that are spinning about the magic angle, trains of short pulses in the manner of Delays Alternating with Nutations for Tailored Excitation (DANTE) allow one to improve the efficiency of the excitation of magnetization compared to rectangular puls ...

Broadband excitation and indirect detection of nitrogen-14 in rotating solids using Delays Alternating with Nutation (DANTE)

Geoffrey Bodenhausen, Simone Ulzega, Marc Anthony Caporini

A train of short rotor-synchronized pulses in the manner of Delays Alternating with Nutations for Tailored Excitation (DANTE) applied to nitrogen-14 nuclei (I = 1) in samples spinning at the magic angle at high frequencies (typically nu(rot) = 62.5 kHz so ...

Long-lived states to sustain hyperpolarized magnetization

Geoffrey Bodenhausen, Jean-Philippe Ansermet, Arnaud Comment, Sami Jannin, Paul Romeo Vasos, Riddhiman Sarkar, Puneet Ahuja

Major breakthroughs have recently been reported that can help overcome two inherent drawbacks of NMR: the lack of sensitivity and the limited memory of longitudinal magnetization. Dynamic nuclear polarization (DNP) couples nuclear spins to the large reserv ...
