Abstract
Oxygen diffusion in low temperature squalane glasses was studied by ph enanthrene phosphorescence quenching and anthracene fluorescence quenc hing in geminate pairs (anthracene...O-2). The oxygen mobility can be described by continuous diffusion. Anthracene fluorescence quenching i n geminate pairs allow to measure diffusion coefficients till 10(-23) cm(2)/s.
