Does the IR spectroscopy align with the product below and if so why? 

**Infrared (IR) Spectroscopy Graph** This graph represents an infrared (IR) spectroscopy spectrum, illustrating the absorption of IR radiation by a sample at different wavelengths. The horizontal axis shows the wavenumber in inverse centimeters (cm⁻¹), ranging from 400 to 4000 cm⁻¹, which corresponds to different vibration frequencies of molecular bonds. The vertical axis represents the transmittance percentage, ranging from 20% to 70%. ### Key Features: - **Wavenumber (cm⁻¹):** - The x-axis is labeled from 400 to 4000 cm⁻¹. Lower numbers correspond to longer wavelengths and higher numbers to shorter wavelengths. - **Transmittance (%):** - The y-axis indicates how much light passes through the sample without being absorbed. Peaks indicate frequencies where absorption by molecular bonds occurred. - **Major Peaks and Their Significance:** - **3300-3400 cm⁻¹:** Broad peaks here often indicate the presence of O-H or N-H stretch (alcohols, amines). - **2800-3000 cm⁻¹:** Peaks in this area typically represent C-H stretching vibrations (alkanes). - **1600-1800 cm⁻¹:** Strong absorption in this region usually suggests C=O stretching (carbonyl groups). - **600-1400 cm⁻¹:** This region, known as the fingerprint region, is complex, indicating various bending vibrations and is often unique for each molecule. This IR spectrum helps identify specific functional groups in a molecule by highlighting characteristic absorption bands, crucial for molecular identification and analysis in chemistry.
