Cyclodextrin complexes with polycyclic aromatic hydrocarbons (PAHs) are interesting in various fields of study, such as environmental work. Our work uses the advantage of excitation-emission matrices (EEMs) in conjunction with PARAFAC to investigate these complexes. This method allows for us to produce separate spectra and concentration data, score values, for the free molecule and its complexes. This work focuses on complexes of β-cyclodextrin with various PAHs. Specifically 1:1 β-cyclodextrin complexes involving naphthalene, anthracene, and phenanthrene are examined. Score values are used to calculate equilibrium constants for the various complexes and compared to literature data. PARAFAC calculated spectra are compared to reference spectra as well.
