**NMR Spectroscopy Analysis** **1. Chemical Information** - **Chemical Formula 1:** C₁₁H₁₄O₃ - **IR Spectrum:** Strong peak at 1720 cm⁻¹ and strong broad peak at 3300 cm⁻¹ **NMR Spectrum Details:** This NMR spectrum displays various peaks indicating the chemical shift of hydrogen atoms (protons) in the given compound: - **2H Peaks:** - Two peaks are observed around the 7-8 ppm range. - **1H Peaks:** - Two smaller peaks in the 4-5 ppm range. - **Additional Peaks:** - A peak at around 2-3 ppm representing 3H. - Another 3H peak in the 0-2 ppm range. **2. Chemical Information** - **Chemical Formula 2:** C₅H₈O₂ - **IR Spectrum:** Strong peak at 1720 cm⁻¹, 1650 cm⁻¹ (note: all peaks integrating to 1H are doublet of doublets) Calculations and notes written above the spectrum indicate a mathematical operation related to integration values for peaks, suggesting calculations associating shifts and splitting patterns to molecular structure details. This NMR and IR spectroscopy data provides crucial information for identifying functional groups and understanding the molecular framework of organic compounds.
