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).

#### Infrared Spectrum Analysis
The image displays an infrared (IR) spectrum graph of an unknown compound. The x-axis represents the wavenumber expressed in cm⁻¹, ranging from 4000 to 500 cm⁻¹. The y-axis shows the transmittance or absorbance levels. Key peaks and troughs are visible within this spectrum, indicating the presence of certain functional groups in the compound.
#### IR Spectrum Features
- **Broad Peak around 3300 cm⁻¹**: This is often indicative of O-H stretching, which may suggest the presence of hydroxyl groups (OH).
- **Sharp Peak near 2200 cm⁻¹**: This may indicate the presence of C≡C or C≡N bonds, suggesting alkyne or nitrile groups.
- **Strong Peak near 1700 cm⁻¹**: Characteristic of C=O stretching, which points to carbonyl groups, possibly indicating ketones, aldehydes, or carboxylic acids.
- **Peaks around 1600-1500 cm⁻¹**: Could indicate C=C stretching, common in alkenes or aromatic compounds.
