Abstract

A simple flash photolysis lamp has been described. This lamp has output in the vacuum uv region down to LiF cutoff and has been used successfully in the photodecomposition of ethane. The output intensity was measured below 1650 Å using carbon dioxide as an actinometer and was found to be 7.2 × 10¹⁶ quanta/flash or 1.31 × 10²¹ quanta/sec. This intensity is about a factor of 10⁶–10⁷ higher than that of the low intensity vacuum uv lamp normally used in the continuous photolysis technique.
