## Abstract The frequencies and intensities of the laser Raman spectra of polyβLβlysine (PLL) have been observed in the following studies: (1) the thermally induced Ξ±βtoβΞ² transition which occurs with increasing temperature at high pH; (2) the ionized form to Ξ± transition at 10Β°C by increasing pH;
The pH-dependent complexation of poly(acrylic acid) (PAA) with phospholipid (phosphatidylcholine) vesicles was characterized by fluorescence polarization, differential scanning calorimetry (DSC), and surface pressure measurements of phospholipid monolayers. The complexation was pronounced below pH 4
