Abstract

Electron spin echo measurements on neutral poly (thiophene) show a clear modulation of the spin-echo decay. Analysis of the modulation and its Fourier transformed (ω) power spectrum indicates that the wave function of the spin defect is extended over ∼ 25 proton nuclei. The functional behavior of the longitudinal relaxation, T1, versus temperature is very similar to that observed previously for (CH)x, although T1 values for poly (thiophene) are significantly longer.
