Question
The image displays a table used for analyzing NMR (Nuclear Magnetic Resonance) spectroscopy data. It includes empty columns and rows for recording details of chemical shifts and splitting patterns. 

**Table Headers:**
- Chemical shift, δ, ppm
- Integration
- Multiplicity Splitting, N + 1
- Adjacent protons, N
- Fragments

**Rows (Entries to be filled):**
- a.
- b.
- c.

**Additional Instruction:**
6. **Conclusion**: Draw structure showing all carbons and hydrogens and match the peaks with the protons.

This layout assists in the identification and analysis of molecular structures based on the behavior of protons in a magnetic field, crucial for chemical education and research.

The image depicts an NMR (Nuclear Magnetic Resonance) spectrum, which is a graphical representation indicating the chemical environment of hydrogen atoms in a sample. 

### Description:

- **Axes:**
  - The horizontal axis (x-axis) is labeled with numbers from 11 to 0, representing the chemical shift in parts per million (ppm). This scale indicates the resonance frequency of the hydrogen nuclei relative to a reference compound.
  - The vertical axis (y-axis) typically represents the intensity of the peaks, which correlates with the number of hydrogen atoms contributing to that signal.

- **Peaks and Assignments:**
  - There are several peaks on the spectrum, corresponding to different hydrogen environments in the molecule.
  - Peaks are labeled with numbers "3", "2", and "3". This likely signifies:
    - **Multiplet structures:**
      - The peak labeled "3" near the 7 ppm region could correspond to an aromatic proton environment, as this is a common region for such signals.
      - The peak labeled "2" near the 1 ppm area typically indicates a methyl group due to its lower ppm value and chemical environment.

### Summary:

NMR spectra are crucial for elucidating the structure of molecules, helping chemists to identify functional groups and understand molecular architecture. The peaks provide insight into the number of hydrogens and their electronic environments, which can be used to deduce the molecular identity.
