Abstract:
Violamycin (VBI) self-associates in aqueous solution at concentration greater than 7 x 10(-5) M. We report in this paper visible spectrophotometric and kinetic experiments that characterize this self-association. We started from a simple dimerization model supported by our experimental data, and we used different methods described in literature for the computation of the dimeric extinction coefficient epsilon d at various wavelengths and the dimerization constant Kd = 9300 M-1.
