The image contains two graphs: a mass spectrum and an infrared (IR) spectrum. ### Mass Spectrum - **Title:** Mass Spectrum - **X-axis:** m/z (mass-to-charge ratio), ranging from 0 to 240. - **Y-axis:** Rel. Intensity (Relative Intensity), ranging from 0 to 100. - **Description:** The mass spectrum illustrates various peaks at different m/z values, indicating the presence and abundance of ions with specific mass-to-charge ratios. - **Inset Table:** Presents three data points: - m/z = 200, Intensity = 100 - m/z = 201, Intensity = 7.7 - m/z = 202, Intensity = 98.2 ### Infrared Spectrum - **Y-axis:** Relative Transmittance, from 0.95 to 1, indicating how much infrared light is transmitted through a sample. - **X-axis:** Wavenumber (cm⁻¹), ranging from 4000 to 500. - **Description:** The IR spectrum shows various absorption bands, indicating different vibrational modes of chemical bonds in the sample. The spectrum exhibits significant peaks where absorption occurs, providing insights into the molecular structure of the compound analyzed. These graphs are essential for analyzing molecular composition and identifying chemical substances.
