Modified electrophoresis technique viz. solution electrophoresis has been employed for the study of the metal ligand equilibira in solution. The method is based upon the migration of metal ion under electric influence in electrophoretic tube with variation in pH of the black ground electrolyte (ionic strength 0.1). The plot of pH Vs absorbance difference reveals the nature of complexation and help in calculating its equilibrium constants. The present work report the result on the binary viz. Cu(II), Ni(II), Co(II) and Zn(II)-Glycyl Leucine complexing system.

The propagation of strong spherical shock in sea water is investigated by CCW method.Effect of overtaking disturbances is included using Yadav techniques Analytical expression for shock velocity and shock strength are obtained for two cases viz. (i) when shock moves freely and (ii) when it moves under the influence of overtaking disturbances. Assuming uniform density distribution, the pressure and particle velocity just behind the shock are obtained for both the cases. Their variation with propagation distance and specific heat index of water are computed and discussed with the help of tables. The results obtained are compared with those obtained by other method.

 A heterogeneous precipitate have been used as ion carriers for the preparation of Na(I) selective membrane sensor. This electrode give near-nernstian responses in the linear concentration range of 1M to 1×10^-5 M with detection limits of the order of 10^-5 M. The stable potentiometric signals are obtained with in a short time period of 4 minutes.The effect of pH and the effect of medium have been studied found to give a better response selectivity coefficient values (log K^pot_Na,M) have been evaluated using fixed interference method.The sensor have also been used as indicator electrode in commercial products.

 In the analysis of crystal binding based on the interionic force model, the contributing arising from coulomb interactions, the dipole-dipole (d-d) and dipole-quadrupole(d-q) interactions and the short-range repulsive interactions of the Hellmann and Varshni-Shukla interaction potential model.The calculated values of Grûneisen parameter, , Anderson Grûneisen parameter using two different formula for each parameter and Second Grûneisen parameter are reported here for alkali chalcogenide crystals(oxides and sulphides) of NaCl-structure. The high pressure behaviour of these crystals has also been studied. The graphical natures of calculated values I.R. absorption frequency-reduced mass and calculated values Debye temperature-reduced mass are also shown. The results obtained here may add a little to the physics and chemistry of these crystals.

Oxidative addition of phenyl ion to Vaska's compound, [IrCl(CO)(Pf₃)₂] in presence of phenyl, parachlorophenyl, paramethoxyphenyl, paraethoxyphenyl and paratolyl derivatives of 1-substituted tetrazoline-5-thione are carried out and structure and mode of metal ligand bonding are investigated using spectral (IR, UV-Vis & `HNMR) and other physico-chemical data. The two Pf₃ molecules are at trans in octahedral [IrCl(CO)(Pf₃)₂(ligand)]BF ₄isolated products.

A heterogeneous precipitates have been as ion carriers for the preparation of Na (I) selective membrane sensor. The electrodes give nearnernstian responses in linear concentration range of 1M to 1x10^-2M with detection limits of the order of 10^-2M . The stable potentiometric signals are obtained with in a short time period of 3 minutes. The effect of pH, and the effect of medium have been studied found to give a better response. Selectively coefficient values (log K^pot_Na,M) have been evaluated using fixed interference method. The sensors have also been as an indicator electrode in commercially available products.

Quantum mechanical calculation of energies, geometries and vibrational analysis of pemoline (2-Amino 5-Phenyl 2-Oxazoline 4-one) were carried out by using ab initio HF and Density functional theory (DFT/B3LYP) methods with 6.31G (d,p) basis set. The optimized geometry parameters obtained by HF and DFT calculations are in very good agreement. The highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) are stimulated. The thermodynamic functions of the title molecule were also performed using HF and DFT methods.
