A Raman study of the hydration of wet-spun films of Li-hyaluronate.
Raman spectroscopy between 620 and 1700 cm(-1) has been performed on wet-spun films of Li-hyaluronate as a function of relative humidity between 54 and 93% at room temperature. The observed vibrational modes show no significant dependence on water content, suggesting that the molecule does not undergo any conformational transitions in this humidity range.
