A method is described using decay, reverse and sine wave birefringence experiments to measure the electrical parameters of acid soluble collagen molecules in solutions containing both monomeric and aggregated forms. Mathematical analysis of decay and reverse signals is performed according to classical limiting low fields equations, and values of permanent and induced dipole moments can be obtained for both molecular species. A confirmation of these results and an evaluation of molecular flexibilities is given by comparison with sine wave birefringence measurements at very low applied fields.
