Flash Photolysis System

The flash photolysis system can perform transient absorption measurements within the short nanosecond range. The absorption spectrum of the formation and decay process of intermediaries in photoreactions such as photodissociation, photoisomerization reaction, etc can be observed. Due to the newly developed software added with the adoption of the optics, transient absorption spectrum measurements in the nanosecond range have been made easier.

  The  light  from  a  high  power  xenon  lamp  is  utilized  for  the  probe  light  and  a  nanosecond  Q-SW  YAG  laser  is  utilized  for  the  pump  light  in  the  flash  photolysis  system.  The  light  is  measured  using  the  multichannel  detector(PMA-11/C8808-01)  equipped  with  a  gate  function  by  switching  the  probe  light  shutter  and  the  pump  light  shutter  with  the  exclusive  software  introduced  with  the  flash  photolysis  optics.  Transient  absorption  measurements  can  be  performed  by  executing  each  spectrum  operation  according  to  nonluminescent  and  luminescent  samples.
