Methanol refractive index

  1. Nov 6, 2007 #1
    I'm looking for Methanol (CH3OH)
    refractive index (n,k) table in Infra Red 2-10micron
    If anyone can help me with that

    What kind of concentration are we talking about? If it's small, you can use the index of water as a good approximation.

    I think the OP needs data for "pure" methanol.

    In my CRC handbook of chemistry and physics, it has a value of 1.3288. But it doesn't tell me at what frequency this value is for.

    Thanks, for your help.
    But Methanol has a "finger prints" at IR range
    that means that frequency dependence can't be ignored.
    (at least for my needs)

    I checked this data base already but all they have it's transmission spectra up to 2.5 micron
