B Absorption bands of liquid and vapor water

  1. Nov 15, 2017 #1
    Water vapor exists at a higher energy state than liquid water...but does that make a difference in the absorption bands? In other words, are the absorption bands of vapor and liquid water identical?

    Thanks!

    Which absorption bands?

    The infrared band is what I'm curious about. Also, my question was worded wrong...since liquid water has, on average, far more hydrogen bonds per molecule than water vapor, shouldn't there be an absorption difference? I would expect liquid water to absorb more strongly than vapor.
