Substitutent and solvent effectson the electronic adsorption spectra of organic molecules, spectroscopy of nonbonded electrons.
The above results show that both the substituent and nitrogen on the N-transition of alkyl iodides are similar to those on the N-alkylamines, and the differences lie in rather three points. This is not surprising because ... -
Time resolved resonance raman studies on photo-induced electron transfer reaction
Time-Resolved Resonance Raman Studies on Proton-Induced Electron Transfer Reaction from Triplet 2-Methoxy-Naphthalene to Benzophenone In this chapter, the effect of solvent polarity on the mechanism and the nature of ... -
Time-resolved resonance Raman spectroscopic studies on photoinduced transients
Transient absorption spectroscopy has been applied to find the relative yield of the radical cations for PVCz and PDBVCz. It has been found that the ratio of the relative yield of the radical cation for monomer to polymer ... -
Studies on the degradative behaviour of polymers containing weak-links of group VI A elements
Unavoidable interaction of aerial oxygen during free-radical polymerization of vinyl monomers results in the formation of weak peroxy linkages in the backbone which dramatically affect the stability of polymers, even though ... -
Studies on the role of vinyl polyperoxides as initiators and polymeric DI and tetrasulfides as chain transfer agents
Terpolyperoxides of styrene, MMA and ?-methylstyrene were synthesized by polymerizing these monomers under excess oxygen pressure by varying the initial feed. The TPPEs have been characterized and it has been shown that ... -
Dharwar stratigraphy and gold mineralisation in Kolar supracrustal belt Karnataka craton India.
The Karnataka Craton is composed of four chief crustal components, viz., the Peninsular Gneiss Complex (PGC), the Sargur Supercrustals, the Dharwar Supercrustals, and the younger granites. The craton is roughly divided ... -
Mechanism of electroreduction of nitrobenzene in alkaline media
Nitrobenzene is shown to give a stepwise reduction in certain media. With a view to examine the factors which influence the scheme of reduction, the effect of different solvents and ionic strengths are examined using tast ... -
Geology Geochemistery and Mineralogy of Mafic-Ultramafic, Gneissic and cordierite Gneiss Enclaves of the south- eastern sector karnataka craton.
This study attempts to decipher the relationships that may exist among the major crustal components in the Eastern Block of Karnataka Craton. Field traverses were undertaken to study the little-known enclaves of (a) ... -
Methyl Methacrylate Styrene
Polymeric peroxides are mainly a class of 1:1 copolymers of vinyl monomers and oxygen. The study of the formation of these polymers has been instrumental in explaining the inhibitory role of oxygen in vinyl polymerization. ...
