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).

![22. In the preparation of the phenyl
diazonium salt, sodium nitrite and
hydrochloric acid were used instead of
directly adding nitrous acid. Why was
nitrous acid prepared in situ?
Sodium nitrite and hydrochloric acid lowers the
temperature of the reaction.
Sodium nitrite and hydrochloric acid are ortho-,
para- directors.
Nitrous acid may deactivate the phenyl ring.
Nitrous acid is unstable and readily decomposes.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2e5d4d3a-455f-41b0-8d75-d93b00e3118d%2F4936dff2-8163-44f8-984d-1b500d350ff4%2Fs45x8g_processed.jpeg&w=3840&q=75)
