🔬 What is NMR Spectroscopy?
NMR (Nuclear Magnetic Resonance) spectroscopy is an analytical technique that exploits the magnetic properties of certain atomic nuclei. It provides detailed information about the structure, dynamics, reaction state, and chemical environment of molecules.
🧪 Method of NMR Spectrum Analysis
Analyzing an NMR spectrum involves a series of systematic steps:
1. Sample Preparation
- Dissolve the compound in a deuterated solvent (e.g., CDCl₃, D₂O).
- Add a standard (e.g., TMS - Tetramethylsilane) for calibration.
2. Acquisition of 1D NMR Spectra
- Run ¹H NMR and ¹³C NMR.
- Choose pulse sequences appropriate for your target nuclei.
3. Interpretation of 1D NMR
- Chemical shift (δ) – Indicates the type of proton or carbon environment.
- Integration – Reflects the number of protons contributing to each signal.
- Multiplicity (splitting pattern) – Reveals coupling between protons.
- Coupling constants (J values) – Measure interaction strength between coupled nuclei.
4. Analysis of 2D NMR (Advanced Study with Dr. Desh Deepak)
2D NMR gives more comprehensive structural insights. Common techniques include:
✅ COSY (Correlation Spectroscopy)
- Reveals proton-proton coupling.
- Helps determine spin systems.
✅ HSQC (Heteronuclear Single Quantum Coherence)
- Correlates ¹H with directly attached ¹³C or ¹⁵N nuclei.
- Provides insight into molecular connectivity.
✅ HMBC (Heteronuclear Multiple Bond Correlation)
- Shows correlations over two or three bonds.
- Useful for assembling larger molecular fragments.
✅ NOESY (Nuclear Overhauser Effect Spectroscopy)
- Detects spatial proximity between protons.
- Helpful in stereochemistry and conformational studies.
