How to determine if this is N- ethylsaccharin or O-ethylsaccharin or a mixture of both based on chemical shifts. 

This is a 1H Nuclear Magnetic Resonance (NMR) spectrum, which is a graphical representation showing the different chemical environments of hydrogen atoms in a molecule.

**Graph Details:**

- **X-Axis:** Represents the Chemical Shift in parts per million (ppm). The values range from approximately 14 ppm to -1 ppm, with a descending arrangement from left to right.
  
- **Y-Axis:** Displays Normalized Intensity, ranging from 0 to approximately 1.0. It indicates the relative number of hydrogen atoms contributing to each peak.

- **Peaks:** Several distinct peaks are visible in the spectrum. Each peak corresponds to hydrogen atoms experiencing different chemical environments within the molecule.

- **Integrated Curves (Red):** The red curves overlaid on the spectrum represent integral values, which quantify the area under the peaks. These values help determine the ratio of different hydrogen environments in the molecule.

- **Highlighted Values:**
  - **4.00 ppm:** A significant peak suggesting a unique hydrogen environment.
  - **1.87 ppm:** Another peak indicating a different environment.
  - **3.03 ppm:** A third distinct environment with a notable peak.

This information can help identify and characterize the molecular structure by confirming the presence of specific hydrogen environments based on their chemical shift values.
