Q4. The following is the ¹3C NMR spectrum of a highly concentrated solution of dicyclopentadiene obtained in chloroform-d. Despite the high purity of the compound based on ¹H NMR, there is a massive peak observed at 77.2 ppm in this 13C spectrum, which doesn't correspond to any resonances expected for dicyclopentadiene. What is this peak, and why do you not see a corresponding peak for this compound in your ¹H NMR spectrum? <-136.22 132.62 222E- 132.23 135 130 125 120 115 110 105 100 95 85 80 75 70 65 60 10'55- · 55 <-50.56 50 45 40 35 wwwww 30
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).
