Tuning crystal structures with weak interactions: From solid solutions to stoichiometric cocrystals
This thesis shows that when two organic compounds A and B are cocrystallized and the
A∙∙∙B interactions are neither completely isotropic nor anisotropic enough to cause the formation
of a stoichiometric cocrystal AxBy, ...
Structural and Solvent Effects on Excited State Dynamics of Rhenium(I) Tricarbonyl α-Diimine Complexes: A Time-Resolved Spectroscopic and Computational Study
The nature of the lowest excited state in rhenium(I) complex with 1,10-phenathroline as ligand was first reported by Mark Wrighton and David. L. Morse. Since then many rhenium(I) complexes with different ligands having ...
Non-covalent interactions in Crystals and Heterocycles of Sulphur and Selenium
Hydrogen bonding plays a very important role in the fields of both chemistry and biology. Conventionally it is represented as D-H---A, where D is the donor atom, A is the acceptor atom and H is the hydrogen atom. It has ...
New NMR Methods with high resolution and sensitivity for rapid data analysis
work is focused on: (i) Development of new fast and sensitivity enhanced NMR methods in solution state and their application to metabolomics and (ii) development of novel NMR methods in solution state for the rapid resonance ...
Computational Study of General Relationships in Chemistry: C−C, C−N, and B−B Coupling, B−B Catenation, and 2D Metal Borides
Elements in the periodic table are categorized into four major blocks, main group (MG) elements, transition metals (TM), lanthanides (Ln), and actinides (An), which differ dramatically. Recent studies revealed some interesting ...
Theoretical Studies of Skewed Spin Ladders and Polycyclic Aromatic Hydrocarbons
This thesis is an effort to understand electronic structure and optical properties of low-dimensional
conjugated molecules such as polyatomic aromatic hydrocarbons and nanoribbons composed
of perylene monomers in addition ...
Microwave Rotation-Tunnelling Spectroscopic and Theoretical Studies on Weakly Bound Molecular Complexes: Intermolecular Bonding across the Periodic Table
Intermolecular interactions appear to be well understood in a broad sense today; at a deeper molecular level, it is still evolving. Spectroscopy in this isolated state proved to be a first step toward understanding the ...
Reversible Redox Switching of First Hyperpolarizability (Β) of Metallorganic Complexes
The concept of molecular switches has garnered enormous interest because of the vital role of these switches as components in molecular electronic/photonic devices, signal transmission and optical communication. Compounds ...
Vanadium Complexes for DNA Crosslinking and Photodynamic Applications
The present thesis work deals with the studies involving synthesis of vanadium-based complexes as photoactivated chemotherapeutic as well a photodynamic therapeutic agent. Their interactions with DNA, as double-stranded ...
Vibrational Spectroscopic studies of Dynamics of BSA unfolding, Lysozyme-Ethanol interaction and Tissue Imaging
Vibrational spectroscopy has served as a powerful tool for understanding various structural properties of the molecules since decades. In the recent years, it has also emerged as an invaluable tool in understanding various ...
