Tiivistelmä
We describe a new spectroelectrochemical method called cyclic spectrovoltammetry. The essence of the method is the application of factor analysis to the spectra recorded during a voltammetric measurement. Factor analysis enables us to use all the information contained in the spectra, a considerable improvement to former techniques employing data at only some wavelengths. When applied to poly(3-methylthiophene), two successive oxidation processes can be observed during the single oxidation peak in the cyclic voltammogram. The usefulness of the method in cases where voltammetric measurements are difficult to interpret is also demonstrated.
