1. Spin-Orbit and Spin-Spin Coupling in the Triplet State
Abstract : The underlying theory of “Spin” of an electron and its associated inter-actions causing internal fields and spectral shift to bulk-magnetism iswell established now. Our understanding of spin properties is significant andmore useful than ever before. READ MORE

2. Combined Quantum Mechanical and Molecular Dynamics study of paramagnetic complexes : Towards an understanding of electronic spin relaxation
Abstract : The prime objectives of contrast agents in Magnetic Resonance Imaging (MRI) is to accelerate the relaxation rate of the solvent water protons in the surrounding tissue. Paramagnetic relaxation originates from dipole-dipole interactions between the nuclear spins and the fluctuating magnetic field induced by unpaired electrons. READ MORE

3. An Analysis of NMRD profiles and ESR lineshapes of MRI Contrast Agents
Abstract : To optimize contrast agent in MRI scan region, e.g. to enhance paramagnetic relaxation in the MRI scan fields(0.1T-3T), one possible way is to slow down the tumbling of the paramagnetic complex. READ MORE

4. Zero-Field Splitting in Gd(III) complexes : Towards a molecular understanding of paramagnetic relaxation
Abstract : The prime objectives of contrast agents in Magnetic Resonance Imaging(MRI) is to accelerate the relaxation rate of the solvent water protons in the surrounding tissue. Paramagnetic relaxation originates from dipole-dipole interactions between the nuclear spins and the fluctuating magnetic field induced by unpaired electrons. READ MORE

5. Some aspects of the slow motion problem in the NMR-relaxation theory : a theoretical study of high spin systems
Abstract : A theory of nuclear spin relaxation in paramagnetic complexes, allowing for the electron spin relaxation to be in the slow motion regime, is presented. The lattice i3 described in terms of the electron Zeeman interaction, a zero field splitting (ZFS) and a Markov operator for the relevant classical degrees of freedom. READ MORE
