Question
Find the major IR Absorption bands and give a proposed molecular composition
**Title: Infrared Spectroscopy Analysis** **Date and Time of Analysis:** Tue, Oct 04, 15:16:53 2022 (GMT-04:00) **Graph Description:** The image displays an infrared (IR) spectroscopy spectrum indicating various absorption peaks. **X-axis:** Wavenumbers (cm⁻¹) ranging from approximately 400 to 4000 cm⁻¹. **Y-axis:** The spectrum’s transmission or absorbance levels are represented on the y-axis. **Key Peaks and Wavenumbers:** - **3028.53 cm⁻¹** and **2931.03 cm⁻¹**: These peaks typically indicate C-H stretching vibrations, suggesting the presence of hydrocarbon groups. - **1694.82 cm⁻¹**: Commonly associated with C=O stretching seen in carbonyl groups. - **1602.84 cm⁻¹**: Possibly indicative of C=C stretching, suggesting unsaturated carbon bonds like those found in aromatic rings. - **1496.54 cm⁻¹** and **1425.85 cm⁻¹**: Associated with bending vibrations in CH₂ and CH₃ groups. - **1368.09 cm⁻¹ and 1407.50 cm⁻¹**: Could be due to further bending or deformation vibrations in methyl groups. - **1299.04 cm⁻¹ and 1216.22 cm⁻¹**: May point to C-O stretching vibrations in alcohols or ethers. - **1080.45 cm⁻¹**: Often attributed to C-O stretching in primary alcohols. - **927.80 cm⁻¹** to **698.08 cm⁻¹**: These peaks can vary, potentially representing out-of-plane bending in aromatic compounds or various skeletal vibrations. **Interpretation:** The spectrum reveals the molecular structure's characteristic functional groups through its peaks. Each peak helps identify specific bond types and functional groups in the organic compound being analyzed. This information is vital for understanding the chemical composition and properties of the substance under study.
