Figure 3. Fluorescence emission spectra for neat and dilute solutions of a light (Brunei) and a heavy (Sales)
crude oil for 300-, 400-, and 790- nm excitation wavelengths. Collisional energy transfer produces large
spectral differences between neat and dilute solutions for short excitation wavelengths. Collisional energy
transfer decreases with increasing excitation wavelength. Determining the contribution of the nascent (dilute
solution) emission to the neat spectrum allows the quantitative determination of collisional energy transfer.
