Transcribed Image Text:**NMR Spectroscopy Analysis for C₁₃H₁₈O₃**
This image presents NMR (Nuclear Magnetic Resonance) spectroscopy data for the compound with the molecular formula C₁₃H₁₈O₃. The image consists of two spectra: a Proton (^1H) NMR spectrum and a Carbon (^13C) NMR spectrum.
### ^1H NMR Spectrum:
- **Range**: The chemical shift range is approximately from 0 to 12 ppm (parts per million).
- **Peaks**:
- There are notable peaks at approximately 0.9, 1.2, 1.5, 2.5, 3.8, and 7.3 ppm.
- Peaks are labeled from 1 to 6, with each label corresponding to specific hydrogen environments within the molecule.
- The peak at 7.3 ppm is labeled 5, indicating an aromatic environment, possibly due to a phenyl group or a similar structure.
- Peaks at lower ppm values, such as around 0.9 and 1.2, suggest the presence of aliphatic hydrogen atoms.
### ^13C NMR Spectrum:
- **Range**: The chemical shift range is approximately from 0 to 220 ppm.
- **Peaks**:
- Several distinct peaks are observed, with significant ones appearing around 20, 60, 125, 130, 150, and 200 ppm.
- These peaks represent different carbon environments in the molecule, with higher ppm values (e.g., 150 and above) typically indicating carbon atoms attached to electronegative elements or involved in double bonds.
### Interpretation:
The ^1H NMR spectrum provides insights into the different types of hydrogen present, showing multiplicity and chemical shift indicative of the chemical environment. The ^13C NMR spectrum provides information about the carbon skeleton, helping to determine the structural framework of the compound.
Together, these spectra allow for the detailed structural analysis of C₁₃H₁₈O₃, enabling the identification of functional groups, aromatic rings, and aliphatic chains.
