Question

How do I find the characteristic infrared absorptions of starting material (4-tert-butylcyclohexanone)

**Infrared Spectrum Analysis** **Analyst:** Student **Date:** Wednesday, November 20, 2019, 8:15 AM **Software Version:** PerkinElmer Spectrum Version 10.03.09 **Graph Description:** - **X-Axis:** Wavenumber (cm\(^{-1}\)) - **Y-Axis:** Percent Transmittance (%T) **Peaks and Bands:** 1. **2945.7 cm\(^{-1}\)**: This peak typically corresponds to the C-H stretch in alkanes and is associated with stretching vibrations of carbon-hydrogen bonds. 2. **2870 cm\(^{-1}\)**: Another peak indicating C-H stretch in alkanes. 3. **1723.2 cm\(^{-1}\)**: This is characteristic of the C=O stretch, typically found in carbonyl compounds like ketones, aldehydes, and carboxylic acids. **Sample Information:** - **Sample Name:** Starting material - **Description:** Sample 076 by Student, Date: Wednesday, November 13, 2019 - **Quality Checks:** The quality checks do not report any warnings for the sample. **Interpretation:** The spectrum indicates the presence of C-H bonds and a strong carbonyl group, suggesting the presence of aliphatic hydrocarbons and possibly a carbonyl compound in the sample. The absence of warnings in the quality checks suggests the data is reliable.

**Characteristic Infrared Absorptions of Starting Material (4-tert-butylcyclohexanone):** | Wave Number (cm⁻¹) | Functional Group | Type of Vibration (Stretch or Bend) | |--------------------|-------------------|-------------------------------------| | | | | | | | | | | | | This table is designed to assist in identifying the characteristic infrared (IR) absorptions of the starting material, 4-tert-butylcyclohexanone. Users are expected to input the specific wave numbers in cm⁻¹, identify the functional groups associated with those wave numbers, and specify whether the type of vibration is a stretch or a bend. This information is vital for understanding the molecular structure and identifying functional groups through IR spectroscopy.
