A method and a device for generating and for detecting a Raman spectrum enables an automated, or automatable, and at the same time quantitative SERD spectroscopy (for example concentration measurement series). To this end, during the SERD spectroscopy, a first spectrum and a second spectrum are standardized in relation to one another in terms of intensity values and a first difference spectrum is subsequently calculated, a second difference spectrum is calculated, the first difference spectrum is converted into a first transformation spectrum, the second difference spectrum is converted into a second transformation spectrum, and the Raman spectrum is calculated by adding the first transformation spectrum and the second transformation spectrum.
