NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.

Question

**Unknowns for 1H NMR Final Report**

**7) Chemical Formula: C₆H₁₁N**

- **IR Spectroscopy:** Weak peak at 3400 cm⁻¹.

**NMR Spectrum Analysis:**

- **Graph Description:**
- The spectrum shows peaks at different parts per million (PPM).
- A peak at approximately 7.5 PPM indicates the presence of aromatic protons (labeled as 5H).
- A peak at approximately 3.5 PPM indicates the presence of 2 protons adjacent to an amine group (NH₂). A hand-drawn structure suggests a CH₃-CH₂-NH₂ group.
- A peak at approximately 1.2 PPM represents 3 aliphatic protons, typically indicative of a methyl group.

**Handwritten Calculations and Notes:**
- The equation "16 + 2 = 18 + 1 = 19 - 11 = 8 / 2 = 4" suggests a step-by-step mass balance or hydrogen count aligned with the spectrum interpretation.

**8) Chemical Formula: C₈H₁₂O₄**

- **IR Spectroscopy:** Strong peak at 1720 cm⁻¹, peak at 1650 cm⁻¹.

**Handwritten Calculation:**
- The note "8 x 2 = 16 + 2 = 18 - 12 = 6 / 2 = 3" possibly relates to structural deductions or hydrogen equivalence.

This analysis provides insights into the structural determination of the unknown compound using 1H NMR spectroscopy alongside IR data.
