DOI: 10.1007/s00216-021-03360-1
Abstract: Raman spectral data are best described by mathematical functions; however, due to the spectroscopic measurement setup, only discrete points of these functions are measured. Therefore, we investigated the Raman spectral data for the first time… read more here.
