Exploring Nanoaggregate Structures of Model Asphaltenes Using Two Dimensional Infrared Spectroscopy
MetadataShow full item record
Asphaltenes have been an enigma in the scientific community; studies on the molecular masses have differed by orders of magnitude and structures have been debated between island or archipelago structures. Thus, the asphaltene community defines asphaltenes by their solubility. Asphaltenes are n-heptane-insoluble and toluene-soluble. The known nanoaggregation of asphaltenes at different timescales and concentrations causes issues to determine the molecular weight and structure of asphaltene molecules. This thesis is the first step to using two dimensional infrared (2D IR) spectroscopy to study ...
