The Interhalogen Cations [Br2 F5 ]+ and [Br3 F8 ]+

Solvation dynamics through Raman spectroscopy: hydration of Br2 and Br3(-), and solvation of Br2 in liquid bromine.

Raman spectroscopy of bromine in the liquid phase and in water illustrates uncommon principles and yields insights regarding hydration. In liquid Br(2), resonant excitation over the B((3)Π(0u)(+)) ← X((1)Σ(g)(+)) valence transition at 532 nm produces a weak resonant Raman (RR) progression accompanied by a five-fold stronger non-resonant (NR) scattering. The latter is assigned to pre-resonance w...

Detection of an Unstable Intermediate in Br Electro-oxidation to Br3 on a Platinum Electrode in Nitrobenzene by Scanning Electrochemical Microscopy

We report the detection of an unstable intermediate generated during Br oxidation to Br3 in nitrobenzene by scanning electrochemical microscopy (SECM), and we attempt to simulate the collection of the intermediate using a proposed mechanism of Br oxidation to Br3 . At a distance of 3.5 mm between the tip and the substrate electrode in the SECM experiment, we observed two waves as we measured th...

Electron attachment to the interhalogen compounds ClF, ICl, and IBr

A Tropical F5 Algorithm

Let K be a field equipped with a valuation. Tropical varieties over K can be defined with a theory of Gröbner bases taking into account the valuation of K. While generalizing the classical theory of Gröbner bases, it is not clear how modern algorithms for computing Gröbner bases can be adapted to the tropical case. Among them, one of the most efficient is the celebrated F5 Algorithm of Faugère....

Zn2(TeO3)Br2

Single crystals of dizinc tellurium dibromide trioxide, Zn(2)(TeO(3))Br(2), were synthesized via a transport reaction in sealed evacuated silica tubes. The compound has a layered crystal structure in which the building units are [ZnO(4)Br] distorted square pyramids, [ZnO(2)Br(2)] distorted tetra-hedra, and [TeO(3)E] tetra-hedra (E being the 5s(2) lone pair of Te(4+)) joined through sharing of e...
