Quadratic Optical Nonlinearity And Geometry Of 1:1 Electron Donor Acceptor Complexes In Solution
(2010-06-04)
The knowledge of geometry of molecular complexes formed via molecular association in solution through weak interactions is always important to understand the origin of stability and function of an array of molecules, ...
Electrochemical Studies Of Polyaniline And Some Of Its Applications
(2010-03-03)
The studies reported in the thesis deal with surface modification of non-platinum metals by coating with electronically conducting polymers, namely, polyanilne (PANI) and polypyrrole (PPY). The oxidation of Г/I2, ...
Chiral Bisphosphinites For Asymmetric Catalysis
(2010-07-21)
Chiral bisphosphinites are well-documented alternatives for chiral bisphosphines as ligands that can be exploited in various asymmpetric syntheses. Particularly, vicinal biarylphophinite ligands give a seven membered chelate ...
Mapping The Reaction Coordinate For The Oxidative Addition Of Molecular Hydrogen To A Metal Center
(2010-07-15)
The binding of molecular hydrogen to a metal center leads to the elongation of the H−H bond and subsequently to its cleavage along the reaction coordinate for the oxidative addition of H2. There has been considerable ...
