Presentation Transcript

  1. ElectronicSpectroscopy NMR Powerpoint Templates

  2. μ = γ I

  3. E = - μ.B0 Nuclear Spins in B0 ΔE = γB0h/2π

  4. Values for H atom • Applied field strength of 7.05T • 1H is approximately 0.120 J/mol, which corresponds to a frequency of 300 MHz • 13C is approximately 0.030 J/mol, which corresponds to a frequency of 75MHz

  5. ω = γB0 Larmour frequency

  6. For 2.35 T (= 100 MHz) and 300 K one gets for 1H a population difference N(α) - N(β) of ca. 8.10-6

  7. Spin Lattice Relaxation

  8. Chemical shift

  9. Chemical shift (δ):The shift in ppm of an NMR signal from the signal of TMS

  10. Direct Coupling 1J

  11. Geminal Coupling 2J diastereotopic

  12. Vicinal Coupling 3J Atoms three bonds apart, the coupling is called vicinal coupling
