The interband dielectric function of nonmetallic YBa2Cu3Ox at energies below 4.5 eV, for E\_I\_ c polarisation, is obtained from transmission and reflection measurements on epitaxial thin films between 1.8 and 473 K. A significant temperature dependence is found, in particular, for the 1.75 eV and 4
