Abstract

Raman and infrared (IR) studies of Na-hyaluronate films have been performed as a function of relative humidity (RH) and temperature. These data show a number of vibrational modes. Certain of these modes are evident in both the Raman and IR data. Changes in the Raman spectra are observed at the order-disorder phase transition (between 84 and 90% RH) and suggest that the molecular conformation changes at the phase transition.
