Solvent effect on electronic absorption spectra of some chlorophenols: Part II - Application of Bakhshiev's theoretical model for elucidating excited state dipole moments and specific solute-solvent interaction energies
215-219A systematic and simple procedure employing Bakhshiev's expression for solvatochromic frequency
shifts in electronic absorption spectra for estimating the excited state dipole moments and specific solute-solvent interaction energies is developed. The results for several chlorophenols based on this method are found to be in close agreement with those obtained by applying the more commonly used McRae's expression-for solvent-induced frequency shifts. The method described herein can be employed as an alternative approach for studying solute-solvent interactions

Thermogravimetric and differential thermal analysis of bipyridyl, <i style="mso-bidi-font-style: normal">ortho</i>-phenylenediamine and 1,10 phenanthroline complexes of some Cu(II) salts
299-302Dynamic
TGA and DTA studies on thermal decomposition of coordination complexes of
bipyridyl, ortho-phenylenediamine and
1.10 phenanthroline with Cu(II) chloride, nitrate, sulphate. acetate and
oxalate reveal that the process occurs through the stages: liquefaction, dehydration,
deamination, deanionation and oxidation of Cu. All the steps are composite in
nature consisting of simultaneous loss of the component moieties in varying proportions
and the related ∆Hs and
Eas are significantly dependent on the
nature of the co-anions and ligands.

Solvent effects on electronic absorption spectra of some chlorophenols: Part I - Excited state dipole moments and specific solute-solvent interaction energies based on McRae's theory
845-853On the basis of McRae's theory [J phys Chem, 58 (1954) 1002] of solvent effect on electronic spectra, a systematic and step-wise procedure for estimating the excited state dipole moments (Il,) of various chlorophenols and their specific interaction energies (Es) with different types of solvents is described. The μe’s estimated by employing only saturated hydrocarbon sovlents are found to be more reliable than those estimated using pairs of polar solvents such as acetonitrile and diethyl ether. The Es values are found to decrease with increase in the number of CI atoms in the solute molecules. Interaction energies of water are generally the largest and those of carbon tetrachloride and diethyl ether are usually negligibly small. The specific interactions in the present solute-solvent systems are electrostatic in nature
