Autor: Johnny N. Naoum, Koushik Chandra, Dorit Shemesh, R. Benny Gerber, Chaim Gilon, Mattan Hurevich

Publikováno v: Beilstein Journal of Organic Chemistry, Vol 13, Iss 1, Pp 806-816 (2017)

Several multistep strategies were developed to ensure single methylation of amines on solid support. These strategies rely on the introduction of the o-NBS protecting/activating group as a key step. We found that the state-of-the-art strategies fail

Absorption Spectra and the Electronic Structure of Gallic Acid in Water at Different pH: Experimental Data and Theoretical Cluster Models

Autor: Natalia V. Karimova, Man Luo, Izaac Sit, Vicki H. Grassian, R. Benny Gerber

Publikováno v: The Journal of Physical Chemistry A. 126:190-197

Gallic acid (GA) has been characterized in terms of its optical properties in aqueous solutions at varying pH in experiments and in theoretical calculations by analyzing the protonated and deprotonated forms of GA. This work is part of a series of st

Energy transfer, pre-reactive complex formation and recombination reactions during the collision of peroxy radicals

Autor: Christopher David Daub, Itai Zakai, Rashid Valiev, Vili-Taneli Salo, R. Benny Gerber, Theo Kurtén

Publikováno v: Physical Chemistry Chemical Physics. 24:10033-10043

In this paper we study collisions between polyatomic radicals - an important process in fields ranging from biology to combustion. Energy transfer, formation of intermediate complexes and recombination reactions are treated, with applications to pero

Tunnel-channel complexes in the Zephyr area, Ontario: potential high-yield aquifers

Autor: S R Slattery, P J Barnett, A J -M Pugin, D R Sharpe, D Goodyear, R E Gerber, S Holysh, S Davies

In south-central Ontario, tunnel channels are primary targets for groundwater exploration due to their potential to contain confined, water-bearing, coarse-grained sediment fills. Despite extensive hydrogeologic and geologic exploration within these

Computed Pre-reactive Complex Association Lifetimes Explain Trends in Experimental Reaction Rates for Peroxy Radical Recombinations

Autor: Christopher David Daub, Rashid Valiev, Vili-Taneli Salo, Itai Zakai, R. Benny Gerber, Theo Kurtén

The lifetimes of pre-reactive complexes, although implicitly part of the equations used to model many gas-phase bimolecular reactions, have seldom been included in quantitative calculations of rate coefficients. Here, we demonstrate the application o

Size-Dependent Onset of Nitric Acid Dissociation in Cs+·(HNO3)(H2O)n=0–11 Clusters at 20 K

Autor: Laura McCaslin, Nan Yang, Mark A. Johnson, R. Benny Gerber, Sayoni Mitra

Publikováno v: The Journal of Physical Chemistry Letters. 12:3335-3342

We report the water-mediated charge separation of nitric acid upon incorporation into size-selected Cs+·(HNO3)(H2O)n=0-11 clusters at 20 K. Dramatic spectral changes are observed in the n = 7-9 range that are traced to the formation of many isomeric
