Zero-Point Vibrational Energy Problem

  1. Oct 21, 2010 #1
    1. The problem statement, all variables and given/known data
    Calculate the zero-point vibrational energies for -O-H and -O-D bonds. If a reaction of these bonds involves breaking them, what does this suggest about the relative rates of reactions of -O-H and -O-D bonds? What should be the ratio of the reaction rates?

    2. Relevant equations
    E(n) = (n + 1/2)*h/2pi(k/m)^1/2 so for zero-point energy n = 0, so E = h/4pi(k/m)^1/2

    3. The attempt at a solution
    I know that m is the reduced mass of the 2 atoms involved in the bonds, so my only problem is that I don't know the k or the force constant of the bonds involved. I've been trying to look on google and such for some sort of table for force constants, but can't seem to find any. Any links, hints, etc.? Any help is appreciated.
