Homework Help: Kerr effect, experiment

  1. Aug 5, 2010 #1
    1. The problem statement, all variables and given/known data

    I what to do a summer physics project on Kerr effect. I want to determine Kerr constant for some molecules. Problem is that i cannot get nitro-benzene and nitro-toluene. Therefor i need to do my research on some other molecules, problem is that i dont have mentor who knows something more about Kerr effect, and i literature and papers I've only found that they did research on some big organic molecules, without explanation why did they used it.

    I would be thankful if someone knows with what molecules i could work, or if someone could recommend some more literature on it.

    2. Relevant equations

    3. The attempt at a solution

    I have 30cm holding tank, 20kV voltage and power-meter that can detect changes of 1nW.
    I've try with water, but power-meter shows smaller value when electric filed is on, possibly because of electro-optic modulating properties of water ?
