1. A MO-SCF study of hydroxyl binding and hydroxyl diffusion in pure and fluorine-containing hydroxyapatite
Sammanfattning : .... LÄS MER
2. Modélisation théorique de la spectroscopie d'actinides des solvatés
Sammanfattning : The framework of this PhD is the interpretation of Nuclear Magnetic Relaxation Dispersion experiments performed on solvated U4+, NpO2+ and PuO22+, which all have an f2 configuration. Unexpectedly the two actinyl ions have a much higher relaxivity than U4+. LÄS MER
3. Traitement de l'interaction spin-orbite en chimie quantique et application à la réactivité des complexes d'actinides
Sammanfattning : The recent methodological developments and the advent of faster computers enable nowadays to investigate theoretically the chemical reactivity of heavy element complexes. As an example we can mention actinide chemistry which is involved in the separation of nuclear wastes. LÄS MER
4. Spin-Orbit and Spin-Spin Coupling in the Triplet State
Sammanfattning : 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. LÄS MER
5. Spin-Spin and Spin-Orbit coupling studies of small species and magnetic system
Sammanfattning : The spin of an electron often misleadingly interpreted as the classical rotationof a particle. The quantum spin distinguishes itself from classicalrotation by possessing quantized states and can be detected by its magneticmoment. The properties of spin and its collective behavior with otherfundamental properties are fascinating in basic sciences. LÄS MER
