Plasmon-induced interfacial charge separation is a promising way to efficiently extract energetic carriers through direct plasmon decay. This mechanism of transfer has been investigated by single-particle scattering spectroscopy, which measures the homogeneous line width. The width broadened transfer, generally known as chemical interface damping. However, conflicting reports exist regarding effect damping on corresponding absorption spectrum, needed accurately determine absolute light conversion efficiencies. work aims resolve this question directly correlating and spectra individual gold nanorods in presence absence charge-accepting interface. We find that for TiO2 coated nanorods, indeed due but overall narrower than Chemical furthermore found increase with larger resonance energies. observed differences widths between are elucidated within context an analytically tractable model describing lowest energy optically bright higher-order dark modes nanorod, including bulk, radiative, effects. Taken together, these results establish spectroscopy capable revealing injection
