Summary

Classical Marcus theory explains electron transfer between molecules and radical cations. Inner-shell bond reorganization energy is key, though steric hindrance in hydrazines can impede electron transfer.

Main Results:

  • Inner-shell bond reorganization energy is the principal factor determining intrinsic reactivity.

Related Experiment Videos

  • Facile electron transfer is generally observed due to sufficient HOMO-LUMO overlap of alkyl groups.
  • Steric effects significantly impact HOMO-LUMO overlap in hydrazines with larger alkyl groups.

    • Conclusions:

    • Marcus theory provides a framework for understanding electron transfer reactivity.
    • Inner-shell reorganization energy and steric factors are critical determinants of electron transfer rates.
