Influence of Biodiesel Content on Fluorescence Anisotropy of Undiluted Diesel-Biodiesel Blends Using Anisotropy-Resolved Multidimensional Emission Spectroscopy (ARMES).

ABSTRACT: The production of diesel-biodiesel blends (DBB) aims to mitigate the environmental impacts of diesel combustion. However, gaps remain in understanding their molecular properties, particularly fluorescence anisotropy (FA), which reflects molecular rotation and environmental constraints (e.g., viscosity, polarity). This property depends on the viscosity and polarity of the medium and understanding it can provide valuable insights for the development of robust analytical methods to evaluate the biodiesel content in undiluted DBB. In this study, anisotropy-resolved multidimensional emission spectroscopy (ARMES) was applied to investigate the FA, providing new insights into the molecular behavior of these mixtures under undiluted conditions. The biodiesel samples were produced through the trans
