### Transcription of Spectroscopy Data#### Molecular Information- **Molecular Formula (MF):** C₈H₁₆O- **Molecular Weight (MW):** 128- **% Carbon (%C):** 74.9- **% Hydrogen (%H):** 12.6#### Infrared (IR) Spectroscopy- The IR spectrum is plotted with % Transmittance on the y-axis and Wavenumbers on the x-axis, ranging from 4000 to 600 cm⁻¹.- Key Absorption Peaks: - Around 2954.08 and 2874.26 cm⁻¹: indicative of C-H stretching. - A sharp peak at 1711.68 cm⁻¹, likely representing C=O stretching. - Peaks at 1460.23 and 1377.20 cm⁻¹: possibly due to CH₂ and CH₃ bending vibrations. - Other peaks include 1169.59, 1109.39, and 721.00 cm⁻¹, suggestive of various C-C and C-O stretching or bending modes.#### Proton Nuclear Magnetic Resonance (¹H NMR)- The ¹H NMR spectrum shows chemical shifts (ppm) on the x-axis, with peaks indicating the environment of hydrogen atoms: - Peaks around 2.5 ppm labeled "1H 1H" likely due to protons on carbons adjacent to electronegative groups. - A peak around 1.5 ppm labeled "2H" indicates protons in a specific chemical environment, possibly adjacent to carbonyl groups. - Peaks labeled "1.5H" around 1.5 ppm suggest overlapping environments. #### Carbon-13 Nuclear Magnetic Resonance (¹³C NMR)- The ¹³C NMR shows peaks with chemical shifts in ppm: - Peaks range between 10 to 100 ppm, common for sp³ hybridized carbon atoms. - Specific peaks can indicate particular carbon types such as methyl, methylene, or methine groups.
