  3. Assumption I: H3C81Br+ 79Br+ 81Br+ H2C81Br+ H3C79Br+/ HC81Br+ C79Br+ H2C79Br+/ C81Br+ HC79Br+ pnt

  4. Assumption I:

  5. Assumption I: Coefficient values ± one standard deviation a = -1072.7 ± 1.92 b = 126.02 ± 0.203 pnt Very good fit! Sqrt(Mw)

  6. Assumption II: ?? 79Br+ 81Br+ H3C79Br+ H3C81Br+ pnt

  7. Assumption II:

  8. Assumption II: Coefficient values ± one standard deviation a = -856.4 ± 22.5 b = 101.82 ± 2.41 pnt Much worse fit than for assumption I CONCLUSION: assumtion I holds, i.e.: Sqrt(Mw)

  9. Conclusion concerning mass assignment for (2+n)REMPI of CH3Br: H3C81Br+ 79Br+ 81Br+ H2C81Br+ H3C79Br+/ HC81Br+ C79Br+ H2C79Br+/ C81Br+ HC79Br+ pnt
