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 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).
draw the strucutre based off the IR spectrum, 1H NMR spectrum, and 13C NMR spectrum for Compound B.

![**IR Spectrum for Compound B**
The IR spectrum graph represents transmittance (%) on the vertical axis versus the wavenumber (cm⁻¹) on the horizontal axis, ranging from 4000 to 500 cm⁻¹. Key features include:
- A broad dip around 3300 cm⁻¹, possibly indicating O-H or N-H stretching.
- A strong peak near 1700 cm⁻¹, typical of carbonyl (C=O) stretching.
- Several smaller peaks between 1000-1500 cm⁻¹, which may denote C-O or C-C stretching.
**¹H NMR Spectrum for Compound B**
The ¹H NMR spectrum illustrates the chemical shift (ppm) on the horizontal axis from 5 to 0 ppm. It contains multiple peaks with specified integrals, such as:
- A small peak at around 4.0 ppm with an integral of 13.7, labeled as (-OH).
- A peak at approximately 3.6 ppm with an integral of 27.3.
- A prominent peak near 1.2 ppm with an integral of 82.0.
- Additional peaks between 0.5 to 1.5 ppm with integrals of 68.4 and 54.7, indicating different hydrogen environments.
These spectra are used to analyze and identify the molecular structure and functional groups of Compound B.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F84066073-0236-4792-806f-3709c1dab065%2F57a73360-5a6c-438e-9a22-18a83d29f8bf%2Fwjlno2x_processed.png&w=3840&q=75)
![**¹³C NMR Spectrum for Compound B (with Proton Coupled Data)**
This graph displays the ¹³C NMR spectrum of Compound B, illustrating the distribution of carbon environments in the compound. The x-axis represents the chemical shift in parts per million (PPM), which ranges from 0 to 70 PPM. The y-axis represents the intensity of the signals.
### Peaks and Splitting Patterns:
- **Triplet at ~68 PPM**: This peak is indicative of a carbon atom with neighboring protons causing a splitting into three peaks.
- **Doublet at ~40 PPM**: This suggests a carbon with adjacent protons splitting the signal into a doublet.
- **Triplet at ~30 PPM**: Similar to the peak at 68 PPM, this peak also represents a carbon interacting with protons to form a triplet.
- **Triplet at ~23 PPM**: This peak presents another triplet pattern, signifying interaction with neighboring protons.
- **Quartet at ~17 PPM**: This quartet indicates a carbon atom coupled with protons, resulting in four closely spaced peaks.
This spectrum is a valuable tool for identifying structural features of Compound B and understanding the coupling of carbon atoms with hydrogen atoms in the molecule.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F84066073-0236-4792-806f-3709c1dab065%2F57a73360-5a6c-438e-9a22-18a83d29f8bf%2Fk6kqsfr_processed.png&w=3840&q=75)
