### ^13C NMR Spectroscopy Overview The presented image shows a ^13C NMR spectrum, which is a type of nuclear magnetic resonance (NMR) spectroscopy used to analyze carbon atom environments within a molecule. #### Spectrum Details - **X-Axis (PPM)** - The horizontal axis, labeled in parts per million (PPM), represents the chemical shift. It indicates the resonance frequency of carbon atoms relative to a standard frequency. - The scale ranges from 0 to about 170 PPM, which covers the typical range for carbon chemical shifts. - **Y-Axis** - The vertical axis indicates the intensity of the signals, representing the relative number of carbon atoms in specific environments. #### Peaks - The spectrum shows multiple distinct peaks occurring across the PPM range. - Peaks observed between 160 to 100 PPM typically correspond to sp^2 hybridized carbons, often indicating aromatic or alkenic environments. - Peaks appearing between 60 to 0 PPM generally represent sp^3 hybridized carbons, often found in alkane or alcohol environments. #### Explanation The various peaks in the spectrum correspond to different types of carbon environments present in the molecule being analyzed. The number of peaks indicates the number of unique carbon environments. ### Final Structure The section labeled "Final structure:" suggests that there is a molecular structure associated with this spectrum, potentially a chemical compound. However, no specific structure is shown in the image provided. This ^13C NMR spectral analysis is crucial in determining the structure and composition of unknown compounds and confirms the presence and position of carbon atoms in various chemical environments.

The image contains the following spectroscopic data and graphs: **MS (Mass Spectrometry) Graph:** - **Title:** MS - **Description:** The graph displays the mass spectrum of a compound. - **X-Axis:** m/z (mass-to-charge ratio) - **Y-Axis:** Relative Intensity - **Feature:** The significant peak is marked as M+ with a value of 159, indicating the molecular ion peak. **Text:** - **Molecular formula:** - **DOU:** (Degree of Unsaturation, value not provided) **IR (Infrared Spectroscopy) Graph:** - **Title:** IR - **Description:** The IR spectrum shows various peaks representing different functional groups in a compound. - **X-Axis:** Wavenumber (cm⁻¹) - **Y-Axis:** Transmittance (%) - **Range:** Extends from 4000 cm⁻¹ to around 500 cm⁻¹, indicating various absorption bands characteristic of molecular vibrations. **¹H NMR (Proton Nuclear Magnetic Resonance) Graph:** - **Title:** ¹H NMR - **Description:** This NMR spectrum displays the chemical environment of hydrogen atoms in the molecule. - **X-Axis:** PPM (parts per million) - - **Notable Peaks:** - Peaks around 7-8 ppm with annotations "2, d," "1, d," "1, d" indicating different proton sets with doublet splitting patterns. - A large singlet at approximately 3 ppm, labeled "3, s," suggests three equivalent protons in a single chemical environment. This information is essential for the structural elucidation of organic compounds in educational contexts.
