Solid-State Fdmr from Sundry Poly(Oxyethylene) Alkylphenyl Ethers - A Verification of the Single-Step Electron-Tunneling as a Cause of the Charge Mobility in Frozen Solids at 4-30-K
Observations of the time-resolved fluorescence-detected magnetic resonance (FDMR) from bridged radical ion pairs generated by pulse radiolysis of micellar aqueous and homogeneous alcohol solutions of poly(oxyethylene) (chain length 5-40) alkylphenyl ethers at 4-30 K are reported. Theoretical analysis of the spectra favors single-step through-bond electron tunneling as a mechanism of the geminate recombination in the pairs at these low temperatures.
