The oscillator strengths of 72 Si I-, Si II- and Si III-lines and multiplets in the wavelength region 1100 -2600 Å were measured in emission. The light source was a wall-stabilized arc burning in argon at atmopheric pressure into which small amounts of silicon tetrafluoride and fluorine were introduced. All oscillator strengths were measured relatively and then put on an absolute scale by using the value Anm  =  1,64 · 10 8  sec -1  for the transition probability of the Si I-multiplet 2506 Å to 2528 Å.
