Figure 2.

Equilibrium titration of OleP with DEO (A) and 6DEB (B) at 298 K. Difference spectra and absorbance intensities (relative inset) of OleP as function of total DEO and 6DEB concentration are reported. Data refer to the absorbance monitored at 417 nm (full dots) and at 382 nm for DEO and 388 nm for 6DEB (empty dots) at a constant concentration of OleP in 50 mM Hepes and 200 mM NaCl, pH 7.5. Lines are the best fit to hyperbolic functions.
