AB  - Photophysical processes in Propidium Iodide (PI), the well known DNA staining 
      dye, have been exploited in homogeneous as well as heterogeneous medium by steady 
      state and time resolved spectroscopy. The DNA staining dye PI exhibits 
      intermolecular proton transfer reaction in aqueous and hydrogen-bonding acceptor 
      solvents due to the formation of quinonoid structure which is acidic in nature. 
      Time resolved emission spectroscopy also predicts the hydrogen bond donor ability 
      of PI. The target dye interacts only with anionic surfactant sodium 
      dodecylsulphate but not with cationic surfactant cetyltrimethylammonium bromide 
      and neutral surfactant Triton X-100 and this interaction is found to be 
      electrostatic in nature. We have further scrutinized the mode of binding of PI 
      with fish sperm DNA. The effect of addition of urea, fluorescence quenching 
      phenomenon, CD measurements reveal that the probe binds to DNA through 
      intercalative style.
