Picosecond Studies of Unimolecular Reactions

Several photochemical reactions occur on a very fast timescale. These ultrafast reactions may best be studied by the use of picosecond spectroscopy. These studies require advanced instrumental and data acquisition techniques. The construction of an apparatus which allows resolution of events on the picosecond timescale is discussed. The streak camera is used as the primary detector in these experiments. Video detection is used to detect signals from the streak camera. A two dimensional digitizer is used to acquire the data from the video detector. This data is then fed to a microcomputer which stores, analyzes and displays the digitized signals. Use of a computer interactive with the two dimensional digitizer allows large signal to noise enhancements.
