Role of Oxygen and BIS(N-arylsalicylaldimino)- Cobalt(II) complexes in radical polymerization.
The technique of DSC has been successfully applied to analyze the exact role of oxygen (either as an initiator or as a retarder) during the radical polymerization of acrylamide. It is found that in the melt polymerization ... -
Role of spin density and interchromophoric coupling in singlet fission
Singlet exciton fission (SEF) is the transformation of a photoexcited singlet exciton into two triplets localized on two chromophores coupled together. This process therefore produces two triplet excitons at the expense ... -

Rotational Specroscopic And Theoretical Investigations Of Non-conventional Hydrogen Bonds
(2014-11-12)The nature of interactions within a molecule, i.e. chemical bonding, is well understood today. However, our understanding about intermolecular interactions, which has great relevance in nature, is still evolving. Historically ... -
Rotational Spectroscopic And Ab Initio Studies On The Weakly Bound Complexes Containing 0-H...π And S-H...π Interactions
(2010-11-22)Work reported in this thesis mainly comprises of the assignments and analysis of the rotational spectra and structures of three weakly bound complexes: C2H4•••H2S, C6H5CCH•••H2O and C6H5CCH•••H2S. All the data have been ... -
Rotational Spectroscopic and Computational Studies on Inter/Intramolecular Bonding
The importance of non-covalent interactions cannot be undermined, as it permeates nearly every sphere of chemistry. The hydrogen bond is the most well-known and ubiquitous non-covalent interaction. In recent times similar ... -
Ru (II)-Catalyzed C−H Activation: Amide-Directed 1,4-Addition of Ortho C−H Bond to Maleimides
Transition metal catalyzed functionalization of C-H bond to C-C bond is advantageous and atom economical. The use of directing groups is intended to overcome the challenges associated with the C-H activation such as low ... -
