It is found that the smallest principal g value g3, being assigned to the axis of the radical, deviates strongly from the free electron value. This behaviour results from partial compensation of the spin and orbital contributions to the g3 value. The measured g3 values in the range of 0.7 yield information about the deviation of the locking potential for the encaged NO from axial symmetry. The estimated 17 meV asymmetry is quite small compared to the situation found for the same radical in polycrystalline or amorphous matrices ranging from 300 to 500 meV. The analysis of the temperature dependence of spin relaxation times resulted in an activation temperature of about 3 K, assigned to temperature-activated motion of the NO within the modified open C60-derived cages with coupled rotational and translational degrees of freedom in a complicated three-dimensional locking potential.","11 Seiten","https://refubium.fu-berlin.de/handle/fub188/28587||http://dx.doi.org/10.17169/refubium-28336","eng","https://creativecommons.org/licenses/by/4.0/","500 Naturwissenschaften und Mathematik::530 Physik::539 Moderne Physik","EPR spectroscopy||NO||C60||Magnetic Resonance||open-cage fullerene||g matrix||encapsulation","EPR study of NO radicals encased in modified open C60 fullerenes","Wissenschaftlicher Artikel","open access","10.5194/mr-1-197-2020","2","Magnetic Resonance","Copernicus Publications","207","197","https://doi.org/10.5194/mr-1-197-2020","2020/1","2699-0016","Physik","10.17169/refubium-27870","Die Publikation wurde aus Open Access Publikationsgeldern der Freien Universität Berlin und der DFG gefördert.","no"
