Several films with different thickness of both beta -methyl sexithiophene and unsubstituted sexithiophene were grown on fused silica by organic molecular beam deposition in ultra-high vacuum conditions and their optical absorption properties were investigated. Because of the different molecular arrangement of the two materials, different optical spectra are observed. By comparing the absorbance spectra of samples of different thickness, the absorption coefficients of both beta -methyl sexithiophene films and sexithiophene films were deduced.

Abstract
Several films with different thickness of both beta -methyl sexithiophene and unsubstituted sexithiophene were grown on fused silica by organic molecular beam deposition in ultra-high vacuum conditions and their optical absorption properties were investigated. Because of the different molecular arrangement of the two materials, different optical spectra are observed. By comparing the absorbance spectra of samples of different thickness, the absorption coefficients of both beta -methyl sexithiophene films and sexithiophene films were deduced.
