Studies on critical phenomena in fluid systems
The coexistence curve measurement of this binary liquid mixture was undertaken mainly because of its very low gravity?affected region. Also, the determination of Tc and the critical concentration are necessary for any ... -
Theoretical studies on impurity models of mixed valent systems
In the first part of this thesis, consisting of the first 3 chapters, calculations of thermodynamic properties like susceptibility, magnetisation and specific heat, and of the single particle spectral density are discussed, ... -
Magnetic Studies at high pressures
Of all the models mentioned, the one that comes closest to explaining the high pressure data on I and II is that due to Zimmermann and König (6). The model now proposed is an extension of a model that has become possible due ... -
Studies in polarization switching characteristics of ferro electrics
Ferroelectrics are characterized by a macroscopic spontaneous polarisation whose direction can be reoriented by the application of a suitable electric field. This reorientation of the ferroelectric polarisation through the ... -
Critical dielectric constant measurements and high pressure phase diagram studies in binary liquid sytem
The main conclusions of the present study have been summarised below. The data have been fitted to the extended scaling equation: C = C? (A t + B t? + …) The present study shows that the exponent (?) characterising the ... -
Study of coupled spin system using two dimensional NMR spectroscopy
Chapter 1 contains a review of various 2D NMR techniques, their applications and an outline of this work. The theory of spin?echo multiple?quantum spectroscopy of strongly coupled spin systems and that of other 2D NMR ... -
study of electrical resistance of bineary liquid mixtures in the critical region
One may now summarize the main findings of this work and also discuss a few additional points for further work. The first important result is that the critical exponent for the divergence of dR/dT in binary liquids has no ... -
Electron spin resonance investigations of some fenoelectric sulphates
The present ESR work on Cu²? in (NH?)?SO? is reportedly the first one on the Cu²? ion doped as an impurity in a trigonal bipyramidal environment in a diamagnetic host lattice. The present study shows that the symmetry of ... -
Some electrical resistivity and High pressure studies in Critical Binary Liquid Systems
Abstract not available -
Mass spectrometric studies of some discharge type ion sources
V.7 CONCLUSION Of all the models mentioned, the one that comes closest to explaining the high?pressure data on I and II is that due to Zimmermann and Konig (6). The model now proposed is an extension of a model that has ... -
Investigations in nuclear magnetic resonance.
From a study of ?Li NMR in single crystals of lithium acetate dihydrate, e²qQ/h and location of the EFG tensor are determined. e²qQ/h = 154.6 kHz, which, being on the higher side of the values obtained for other Li compounds, ...
