### Rotational-Vibrational IR Spectrum of DCI **Introduction:** Presented below is a segment of the rotational-vibrational IR spectrum of DCI, where D represents deuterium (²H). The IR spectrum is characterized by specific peaks that correspond to distinct vibrational transitions within the molecule. Each peak is annotated with its wavenumber value, measured in cm⁻¹. **Graph Explanation:** - **X-Axis (Wavenumber, cm⁻¹):** The horizontal axis represents the wavenumber, indicating the frequency of the IR light absorbed by the molecule. - **Y-Axis (Absorbance):** The vertical axis measures the absorbance, indicating how much IR light the molecule absorbs at each wavenumber. **Identified Peaks:** The IR spectrum exhibits several sharp peaks, each corresponding to a specific vibrational transition within the DCI molecule. These peaks occur at the following wavenumbers: - 2073.5 cm⁻¹ - 2065.6 cm⁻¹ - 2049.5 cm⁻¹ - 2046.9 cm⁻¹ - 2077.9 cm⁻¹ - 2078.1 cm⁻¹ - 2100.1 cm⁻¹ - 2100.6 cm⁻¹ - 2109.7 cm⁻¹ - 2111.6 cm⁻¹ - 2116.0 cm⁻¹ - 2121.3 cm⁻¹ - 2123.6 cm⁻¹ - 2124.0 cm⁻¹ - 2131.1 cm⁻¹ - 2131.7 cm⁻¹ - 2140.8 cm⁻¹ - 2143.7 cm⁻¹ Each of these peaks corresponds to a rotational-vibrational transition unique to the DCI molecule and arises due to changes in the energy levels of molecular bonds when absorbed with specific IR light frequencies. ### Conclusion: The rotational-vibrational IR spectrum is a valuable tool in understanding the molecular structure and bonding within DCI. By analyzing the positions and intensities of these peaks, one can infer important information about the molecular vibrations and rotations, aiding in the study of molecular dynamics and chemical properties.

### Understanding Isotopic Peaks in Chemical Analysis Each peak shows a doublet because of the presence of the two isotopes of chlorine, \(^{35}Cl\) and \(^{37}Cl\). Which isotope is responsible for the taller of the peaks in each doublet? [From here on out, we will work with that isotope.] #### Detailed Explanation: In mass spectrometry and other analytical techniques, peaks can appear as doublets due to the presence of isotopes. For chlorine, the isotopes \(^{35}Cl\) and \(^{37}Cl\) create such doublets. Identifying which isotope contributes to the taller peak is crucial for accurate analysis and further experimentation. Isotope abundance typically dictates peak height in a spectrum. The more abundant isotope, \(^{35}Cl\), often results in the taller peak of each doublet. In subsequent discussions and interpretations, this isotope will be used for consistency and clarity in the analyses.
