The main goal of the Laboratory is to expand the boundaries and conventional applications of the magnetic resonance approaches for petrophysical research. Under the "magnetic resonance approaches" we mean first of all different techniques of electron paramagnetic resonance (EPR) also known as electron spin resonance (ESR) and nuclear magnetic resonance (NMR). We investigate crude oils, their products and fractions at different conditions to understand the behaviour of the paramagnetic centres (unpaired electrons) in the complex environments and follow the structure and dynamic changes of the investigated species.
