The toluene proton NMR spectrum, consisting of two peaks due to the methyl and aromatic protons, has been recorded at 55.0 MHz and 1.29 T. (a) What would the magnetic field be at 500. MHz? 4.0 (b) At 55.0 MHz, the resonance frequencies are methyl: 128 Hz; aromatic: 394 Hz. What would the frequencies be using a 500. MHz spectrometer? methyl 4.0 Hz aromatic 4.0 Hz (c) Calculate the chemical shifts (8) of the two signals, using both the 55.0 MHz and 500. MHz data. methyl at 55.0 MHz 4.0 ppm aromatic at 55.0 MHz 4.0 ppm methyl at 500. MHz 4.0 ppm aromatic at 500. MHz 4.0 ppm
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).
