• . Prominent examples are SERS and TERS, where the intrinsically small Raman scattering cross-section is enhanced by several orders of magnitude, making single-molecule spectroscopy feasible. These spectroscopic techniques have shown tremendous progress in the last two decades [29][30][31][32]. Under high

• hybridization, charge transfer and screening [1][2][3][4]. These effects lead to a broadening and shift of the molecular resonances [5]. Often the molecular functionality is also lost due to these interactions [6]. However, addressing individual molecules in devices or by single-molecule spectroscopy as offered

• increasingly sophisticated and versatile. These developments have made optical single molecule spectroscopy an indispensable tool to address complex problems in chemistry [1][2][3], in material sciences [4][5][6], and in life sciences [7][8][9][10][11].

• investigations of quantum dots, we expect single molecule excitation spectroscopy to become a valuable addition to the established single molecule spectroscopy methods. The approach will not only aid in the analysis of isolated dyes or nanoparticles but also prove valuable in analyzing complex emitting systems
