Analysis and extraction of molecular hyperpolarizability from on and off resonance hyper-Rayleigh scattering measurements in solution : Ferrocenyl donor-organic acceptor and -(P=N)- linkage based donor acceptor molecules as case studies
Knowledge of accurate second?order nonlinearity or first hyperpolarizability (?) of organic and organometallic molecules is important in a variety of applications. The second?order response from a molecule in solution is ... -
Dynamics of I*(2p1/2) production in the UV photodissociationof alkyl iodides
The photodissociation dynamics of alkyl iodides in their A?band of absorption (arising from n ? ?* transition) has been of interest for dynamicists for the past three decades, starting from the pioneering work of Kasper ... -
Studies in the electro deposition of manganese
The investigations described in the thesis have been directed towards an understanding of the mechanism of electrodeposition of manganese from manganese sulphate–ammonium sulphate solutions and towards an elucidation of ... -
Aspects of the chemistry of copper(II) complexes having different nuclearity
Synopsis of the thesis entitled “Aspects of the chemistry of copper(II) complexes having different nuclearity” to be submitted by Mrs. K. Geetha under the supervision of Prof. A. R. Chakravarty of the Department of Inorganic ... -
Studies on the synthesis, structure and reactivity of amino and halo silanes
Tri(amino)silanes are generally prepared by the condensation route: HSiCl? + 6 R?NH ? HSi(NR?)? + 3 R?NH·HCl Even though these compounds have been extensively used both in industry and chemistry, only very little is known ... -
Electrochemistry at complex interfacial geometries
A study of electrochemical response of interfaces, when one or more of the electrodes assume arbitrary or rough (random) geometries, is of utmost importance but is difficult to analyse. The importance arises from the fact ... -
Magnetism and exchange in the layered transition metal thiophosphates and their solid solutions
It was mentioned in the Introductory Chapter that changes in the magnetic behaviour of the intercalation compounds of the transition metal thiophosphates depend crucially on the magnetism of the host lattice. Hence an ... -
Copper (I) promoted allylic nucleophilic substitution: a synthetic and mechanistic study.
Abstract not available -
Electrode kinetics of hydrogen evoluion reaction & electrodeposition of silver, palladium & silver-palladium alloys.
It has been demonstrated that chemically modified manganese dioxide can be prepared by oxidation of appropriate mixed salt solutions by chlorate ion. Manganese dioxide–coated titanium electrode has been found to be ... -
Studies on the synthesis and oxidation of substituted hydrazines
The thesis pertains to investigations relating to the synthesis and oxidation of substituted hydrazines. The contents of this thesis can be categorised into two parts. The first part concerns the synthesis of hydrazines ... -
Application of electrochemical kinetics to predict the failure modes of nickle cadmium cells
A critical review of the literature on nondestructive techniques to predict failure modes of sealed rechargeable battery-cells, such as nickel-cadmium cells, has been made. It is thus concluded that a.c. impedance measurements ... -
Studies of hydrazinium salts
The present investigation aims at synthesis, characterization, reactivity, thermal properties and applications of some of the hydrazinium salts. In the introductory Chapter, a literature survey on the chemistry of hydrazine ... -
Studies on high energy hydrazine compounds
The present investigation aims at synthesis, characterisation, reactivity, thermal properties and applications of some of the high?energy materials of hydrazine. The chemistry of hydrazine is of interest because of its ... -
Aminolysis reactions of octachlorocycloterathophazene, Ph.D. Thesis
3–12. Conclusions – The present work embodies the first systematic investigations of the reactions of octachlorocyclotetraphosphazene with two primary aliphatic amines, viz., ethylamine and t-butylamine. In both cases, in ... -
Physical adsorption from mixtures of gases-Thesis submitted for the Degree of Doctor of Philosophy In the faculty of Science
The thesis deals with a study of the adsorption from binary mixtures of gases on solid surfaces. A major part of the investigations is carried out on silica gel, while a part of the work consists of an investigation on ... -
Electronic structure and spectroscopy properties of some thicarboy compounds
8.1 SEMI-EMPIRICAL PARAMETERS Different sets of bonding parameters in the CNDO/2 formalism and various approximations for evaluating the off-diagonal matrix element in the SCC-EH method were employed for a group of thioamides ...
