For example, in the TMS, we found the magnitude of the shift depends on the absorbance of the dye in different solvents and their refractive indices, which depend on the magnitude of London dispersion forces and the mirrors' absorbance and transmittance/reflectance values. The data for three representative cases of methanol, butanol and nonanol are presented on Fig. . The uncertainty in the thickness of the gold layer produced by sputtering may have additionally contributed to higher levels of reflection.
