Abstract

These files contain data along with associated output from described analysis supporting all results reported in Yu, Z.; Frontiera, R. R. Intermolecular Forces Dictate Vibrational Energy Transfer in Plasmonic–Molecule Systems. ACS Nano, 2022, 16, 1, 847–854. Anti-Stokes and Stokes scattering from aromatic thiols adsorbed on gold nanoparticles are monitored with ultrafast surface-enhanced Raman spectroscopy (SERS). Vibration population ratio changing kinetics of the aromatic thiols is obtained by conducting peak fitting with the acquired ultrafast anti-Stokes and Stokes SERS spectra and performing Boltzmann analysis. The as-obtained kinetic traces are fitted with exponential decay convoluted with the instrument response function to extract the temporal increase and lifetime of the population ratio kinetics, which are found to be correlated with the molecular property in a fashion that molecules with a stronger intermolecular interaction experience less temporal population ratio increase and shorter excited vibrational state lifetime.

Description

Data including the raw spectra, the fitting code and the fitting procedure are stored as Igor .pxp files. Numeric output from the fitting recorded in spreadsheet is included. A README file containing the connection between the data files and the noted nomenclature of the datasets is provided.
