This image appears to be an infrared (IR) spectroscopy graph, which shows the transmittance of a sample across different wavenumbers (cm⁻¹). Here’s a detailed explanation suitable for an educational context: ### Graph Explanation **Axes:** - **X-axis:** Wavenumbers (cm⁻¹), ranging from 4000 to 500 cm⁻¹. This axis represents the frequency of light, with higher wavenumbers corresponding to higher energy. - **Y-axis:** Percentage Transmittance (%), ranging from 0 to 26%. This indicates how much light passes through the sample at each wavenumber; lower transmittance corresponds to higher absorption. ### Key Features 1. **Broad Peak around 3488.64 cm⁻¹** - **Annotation:** "OH" - **Interpretation:** This broad peak is characteristic of O-H stretching vibrations, often indicating the presence of alcohols or phenols. 2. **Series of Peaks from 2971.78 to 2852.03 cm⁻¹** - **Annotations:** "CH" (multiple places) - **Interpretation:** These peaks are typically associated with C-H stretching vibrations, common in alkanes. 3. **Peak at 2358.86 cm⁻¹** - Unlabeled; could suggest the presence of some functional group like CO₂ but would need further context. 4. **Peak at 1717.0 cm⁻¹** - **Annotation:** "C=O" - **Interpretation:** This is indicative of carbonyl group (C=O) stretching, suggesting the presence of ketones, aldehydes, or carboxylic acids. 5. **Specific Peaks around 2260.97 and 2101.50 cm⁻¹** - **Annotation:** "C≡C" (twice) - **Interpretation:** Indicates the presence of a carbon-carbon triple bond, found in alkynes. 6. **Additional Peaks:** - **1457.92 and 1377.0 cm⁻¹:** Often related to bending vibrations of CH₂ and CH₃ groups. - **Other minor peaks** in the fingerprint region (1500 to 500 cm⁻¹), which provide more specific information about molecular structure. ### Conclusion The IR spectrum provides insights into the functional groups present within the sample
