The vibrational spectra of methyl groups in methylthiolate and methoxy adsorbed on Cu(100)

• We show that the difference in the infrared vibrational spectrum of C-H stretch modes arising from the methyl group of two surface intermediates, methylthiolate and methoxy, originates from the difference in the methyl deformation modes frequencies of the two intermediates. Importantly, while the vibrational fingerprint of the two methyl groups are not transferable between the intermediates, the Fermi resonance coupling constants of the methyl group are.
