Raman and FTIR spectroscopies of fluorescein in solutions

Raman and Fourier transform-infra red (FT-IR) spectroscopies of fluorescein in aqueous solutions have been investigated in the pH range from 9.1 to 5.4. At pH 9.1 fluorescein is in the dianion form. At pH 5.4, fluorescein is a mixture of monoanion (∼85%), dianion and neutral forms (together ∼15%). T...
