In Raman spectroscopy fluorescence (that is emission of unwanted light) is a persistent problem. Surprisingly, it has been discovered that a way to avoid this fluorescence is to excite the Raman spectra with deep ultraviolet (DUV) light. “Fluorescence does not exist if the exciting light has a wavelength shorter than 260 nm” . The DTU project has accordingly been started to get experience with the use of DUV-laser light in Raman spectroscopy to characterize samples that with visible light would be strongly fluorescing. This method has only – over the many years since 1984 – been very sparsely investigated. We foresee many applications of results of the DUV Raman method. A main focus is on characterization of food and oil products. The DUV Raman technique – when implemented – will help oil characterization and identification of waste products found at sea and shores. Small amounts of polycyclic aromatic hydrocarbons (PAHs) and sulfur-containing compounds contained in oil products should be detectable (on a ppm to ppb scale or less).
