Introduction Of Infrared Spectroscopy

Introduction

• Infrared Spectroscopy is one of the impertant spectroscopy for the assignment of the structure of an unknown compound.
• All the compound having covalant bond,whether organic or inorganic,absorb various frequency of electromegnatic radiation in the infrared region.
• The absorption in infrared radiation can be expressed either in terms of wavelength(λ) or in wave number(v).
• In terms of wavelength(λ) the IR region lies between 2.5μm to 25μm (1μm= 10^-6 cm , 1nm = 10^-9 cm)
• The relationship between wavelength and wave number is as Follow: Wave Number(v) = 1/Wavelength (cm)
• Wave number Unit is cm^-1
• In organic Compound Infrared Spectra Plotted as percentage transmittance against wave numberv(4000-600 cm^-1)
