Time-resolved spectroscopy reveals how vibrational and solvent motions affect electron transfer dynamics in alcohol solutions, indicating a major role for molecular motions.

Key Points

This research aims to explore the dynamics of intramolecular charge transfer in specific compounds in alcohol solutions, focusing on vibrational and solvent motions.
Used time-resolved emission spectroscopy to analyze charge transfer in dimethylaminobenzonitrile (DMABN) and diethylaminobenzonitrile (DEABN).
Examined the temperature effect on population decay in various alcohol solvents.
Fitted population decay data to both single and multiexponential functions to assess local excited state lifetime dynamics.
For DMABN in alcohol solutions, population decay in longer chain alcohols was best described by a multiexponential function.
Average lifetime of the LE state was found to be faster than the characteristic solvent fluctuation rates.
Comparison with theoretical models indicated that vibrational motions in the molecule significantly impact the rate of reaction more than solvent diffusion.
