**Title: Mass Spectrum of Aniline**

**Description:**

This diagram represents the mass spectrum of aniline, displaying the relative intensity of ion signals detected across various mass-to-charge ratios (m/z).

**Key Features:**

- **X-Axis (m/z):** This axis represents the mass-to-charge ratio of the detected ions, ranging from 0 to 100.

- **Y-Axis (Relative Intensity):** This axis shows the relative intensity of the ions, ranging from 0 to 100. The intensity indicates the abundance of ions at each m/z value.

- **Major Peak:** The most prominent peak is observed at m/z 93, suggesting that this is the molecular ion peak representing aniline (C6H5NH2). This peak indicates the highest ion abundance at this specific mass-to-charge ratio.

- **Fragment Peaks:** Additional smaller peaks are observed, indicating the presence of fragment ions resulting from the ionization process. These fragments provide insights into the structural features of aniline.

**Summary:**

The mass spectrum is a critical tool used in analytical chemistry to identify the composition and structure of chemical substances by analyzing ionized fragments. This spectrum of aniline helps in understanding its molecular weight and possible structural components.
