Sažetak
The impact of geometrical frustration on electron spin decoherence pathways is studied by electron paramagnet- ic resonance spectroscopy (EPR) at X- and W-band frequencies. The glassy and crystalline state of solid ethanol served as a simple model of two extreme realizations of host molecular packing probed by relaxation behavior of incorporated paramagnetic nitroxyl radical TEMPO. The specific molecular dynamics is revealed as arising from the local disorder of the environment, suggesting the importance of nuclear spin bath coupling with the electron spin. It is proposed that spectral diffusion might be useful indicator of the extent of frustration in disor- dered/glassy matrices.
