Abstract
The effect of molecular hydrogen on the attenuation spectra of single-mode optical fibres has been studied at ambient temperatures for a range of hydrogen pressures. From studies of the analogous deuterium spectra, peaks observed in the 1.0¿¿1.3 ¿¿m region have been assigned to combination vibrational absorption effects, with two new peaks having been identified at 1.143 and 1.33 ¿¿m. An out-diffusion coefficient of 1.4 ¿¿ 10¿¿11 cm2 s¿¿1 has been determined for deuterium in silica fibres at 20¿¿C.
