Analyzing Infrared Spectra
The electromagnetic radiation or frequency is classified into radio-waves, micro-waves, infrared, visible, ultraviolet, X-rays and gamma rays. The infrared spectra emission refers to the portion between the visible and the microwave areas of electromagnetic spectrum. This spectral area is usually divided into three parts, near infrared (14,290 – 4000 cm-1), mid infrared (4000 – 400 cm-1), and far infrared (700 – 200 cm-1), respectively. The number set is the number of the wave (cm-1).
IR Spectrum Of Cyclohexanone
It is the analysis of the structure of cyclohexaone using IR data interpretation.
IR Spectrum Of Anisole
Interpretation of anisole using IR spectrum obtained from IR analysis.
IR Spectroscopy
Infrared (IR) or vibrational spectroscopy is a method used for analyzing the particle's vibratory transformations. This is one of the very popular spectroscopic approaches employed by inorganic as well as organic laboratories because it is helpful in evaluating and distinguishing the frameworks of the molecules. The infra-red spectroscopy process or procedure is carried out using a tool called an infrared spectrometer to obtain an infrared spectral (or spectrophotometer).
![**Question 9: Using the provided chart, predict the \( ^1H \) NMR spectrum of phenacetin.**
The image includes a chemical structure of phenacetin with labeled hydrogen atoms, and a table for predicting the \( ^1H \) NMR spectrum.
**Chemical Structure:**
- The chemical structure of phenacetin shows various hydrogen atoms labeled as \( a, b, c, d, e, \) and \( f \).
**Table for Predictions:**
- **Assignment:** Labels for each hydrogen as \( a, b, c, d, e, f \).
- **Expected ppm:** Space for entering expected chemical shift values in parts per million (ppm) relevant to each hydrogen label.
- **Expected integration:** Space for entering the expected integration, corresponding to the number of hydrogens causing the peak.
- **Expected multiplicity:** Space for stating the expected multiplicity of each signal, indicating the splitting pattern.
This setup is used for students to fill in the details on predicted chemical shifts, integrals, and multiplicities of protons in phenacetin using \( ^1H \) NMR data.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F12642ddc-0baa-4782-abc5-60ff8a4ca3b1%2Fb4b760ee-4e4c-4716-a34d-4727e0f98f70%2Ffrn73gj_processed.jpeg&w=3840&q=75)
