Differential scanning calorimetry (DSC) and fluorescence polarization methods have been used to study the interactions between phospholipid membranes and a polymeric biocide, poly(hexamethylene biguanide hydrochloride) (PHMB). It was found that PHMB had very little effect on neutral lipids such as phosphatidylcholine (PC) and phosphatidylethanolamine (PE),(More)
Asymmetric charge transfer (CT) spectra from combinations of carbazole derivatives and chloranil are shown to consist of two bands originating from the highest (HOMO) and second highest (HOMO 2) energy occupied molecular orbitals of carbazole. Symmetry arguments are used to indicate tha t of two possible (parallel plane) alignments of donor and acceptor, t(More)
