  1. 1. Simulation of Relaxation Processes in Fluorescence, EPR and NMR Spectroscopy

    Författare :Pär Håkansson; Per-Olof Westlund; Yehudi K. Levine; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; EPR; NMR; Energy migration; bicontinuous cubic phase; Stochastic Liouville Equation; Brownian Dynamics; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Relaxation models are developed using numerical solutions of the Stochastic Liouville Equation of motion. Simplified descriptions such as the stochastic master equation is described in the context of fluorescence depolarisation experiments. Redfield theory is used in order to describe NMR relaxation in bicontinuous phases. LÄS MER
