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).
IR spectra deals results from the interaction of infrared radiation with matter by absorption. IR spectra uses the IR radiation for the excitation of a molecule and thereby generate the IR spectrum as a function of frequency or wavelength of light. IR spectra has been used as a finger print to identify chemical compounds or functional groups.
Mass spectrum is the technique used in analytical chemistry for the separation of ions based on the mass to charge ratio which basically ionizes chemical species in the ionization chamber of a mass spectrometer. Fragmentation is the breaking up of unstable molecular ions which is usually formed in the ionization chamber of a mass spectrometer. These fragments will cause a pattern in the mass spectrum.
Every nuclei will have spin and if an external magnetic field is applied, there will be an energy transfer which corresponds to radio frequencies. NMR shows different frequencies which corresponds to different kind of protons in an unknown organic compound.
