mina (4 x 20 cm) and further purified by column separation. For this procedure, the dye was dispersed in acetic ester and added to the chromatographic column as well as the solid particles and eluted with acetic ester until nearly colourless. Then the dye is collected with chloroform/acetic acid (10
The systematic presence of a spectrum has been observed that has been termed anomalous SERS in the spectra on silver sols of a set of monocarboxylic acids, characterized by being independent of the adsorbate that is initially added and whose bands cannot be correlated with the respective Raman solut
