Physical Chemistry Chapter 14

  1. Stark Effect
    Splitting of spectral lines due to the presence of a strong electronic field
  2. Zeeman Effect
    Splitting of spectral lines due to the presence of a strong magnetic field
  3. Centrifugal Distortions
    Spinning of the atom causes the bond to elongate
  4. Non-linear modes of vibration
    3(n)-6
  5. Linear modes of vibration
    3(n)-5
  6. IR requires?
    non-symmetrical molecule
  7. Bond Order
    ((#of electron bonding)-(# of anti bonding))/2
  8. Rotational Spectroscopy
    • ΔE=2B(J+1) 
    • 2B is the energy separation between states 
    • 1->2-----2B
    • 2->3-----4B
  9. Symmetric stretching
    Two atoms stretch at the same time and are attached to a center atom
  10. Asymmetrical stretching
    Two atoms stretch at different times and are attached to a center atom
  11. Scissoring (Bending)
    Two atoms are bent towards each other then bent back
  12. Rocking
    movement in one direction then back to the other
  13. Wagging
    moving towards then back again
  14. Twisting
    One atom moves forward while the other moves back about the center atom
