Normal mode analysis of γ form of oleic acid

Oleic acid is one of the major components of a variety of oils and its spectra are very complex due to the presence of a large number of conformational states (α, β, γ). In the present communication, an attempt has been made to unravel the complex spectra by calculating the normal modes and examining the spectral features such as line position, line width, band intensity, group frequency concept and spectral relationship between the finite and infinite systems.
