  5. Outline • Compare molecular-ion clusters of real and ideal BrmCln compounds • Discover a chlorine rule for BrmClncompounds • Apply the chlorine rule to three spectra

  6. Ideal Model = Binomials (a + b)m(3a + b)n Br1Cl1 (1:1)1(3:1)1 = 3:4:1

  7. Ideal Br1Cl2 (1:1)1(3:1)2 = 9:15:7:1

  8. Chlorine Constant

  9. Bromine Constant

  10. Chlorine Rule for Ideal Compounds IM = 3n When IM = 1, 3, 9, 27 or 81; then n = 0, 1, 2, 3, or 4, resp.

  11. Summary • Find n in BrmClnfrom molecular-ion cluster • Find m from number of cluster peaks • Chlorine rule: a new tool for use in structure determinations
