### Spectroscopic Analysis of a Compound Containing Exactly One Oxygen Atom

This educational module provides an analysis of a compound with a single oxygen atom using three different spectroscopy methods: **¹H NMR (Proton Nuclear Magnetic Resonance), ¹³C NMR (Carbon-13 Nuclear Magnetic Resonance), and IR (Infrared) Spectroscopy.** The integration ratios for the ¹H NMR spectra are given as 1:6. Below are details and interpretations of the provided spectra.

#### 1. Infrared (IR) Spectroscopy
- **Graph Description**: The IR spectrum is plotted with % Transmittance on the y-axis and Wavenumbers (cm⁻¹) on the x-axis, ranging from 4000 to 500 cm⁻¹.
- **Analysis**:
  - A broad, strong absorption near **3400 cm⁻¹** suggests the presence of an **O-H (hydroxyl) group**.
  - Sharp peaks around **2900 cm⁻¹** indicate **C-H stretching vibrations** typical of alkyl groups.
  - Additional significant absorptions around **1700 cm⁻¹** point towards a **C=O (carbonyl) group**, which suggests the presence of a ketone, aldehyde, ester, or carboxylic acid functional group.
  - Fingerprint region (1500–500 cm⁻¹) shows a mostly unique pattern used for identifying the specific compound.

#### 2. ¹H NMR (Proton Nuclear Magnetic Resonance) Spectroscopy
- **Graph Description**: The ¹H NMR spectrum shows Chemical Shifts (ppm) on the x-axis and signal intensity on the y-axis.
- **Analysis**:
  - Signals between **3 to 4 ppm** with an integration ratio indicating a **–CH group** coupled with neighboring hydrogen atoms.
  - Multiple peaks between **1 to 2 ppm**, forming a complex splitting pattern, suggest the presence of multiple adjacent alkyl groups.
  - The integration ratio of **1:6** supports either a single unique hydrogen environment compared to six equivalent hydrogens or two environments in this ratio, which can indicate structural features such as isopropyl groups or terminal methyl groups.

#### 3. ¹³C NMR (Carbon-13 Nuclear Magnetic Resonance) Spectroscopy
- **Graph Description**: The ¹³C NMR spectrum
