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

### 2.) How many ¹H-NMR and ¹³C-NMR resonance signals would you expect in each spectrum for 2-aminophenyl phenyl sulfide?

#### Compound Structure:
The structure of 2-aminophenyl phenyl sulfide is shown above. It consists of two phenyl rings connected by a sulfur atom. One of the phenyl rings has an amino group (-NH₂) attached to it at the ortho position.

#### ¹H-NMR Spectrum:

- **Chemical Shifts and Assignments:**
- **Peak A:** 7.447 ppm
- **Peak B:** 7.22 ppm
- **Peak C:** 7.21 ppm
- **Peak D:** 7.10 ppm
- **Peak E:** 7.09 ppm
- **Peak F:** 6.77 ppm
- **Peak G:** 6.75 ppm
- **Peak J:** 3.27 ppm

Peaks B and C have overlapped with the solvent peak, which has not been removed from this spectrum.
