Abstract :
Terahertz time-domain spectroscopy has been used to analyze the mixed samples of different mass ratio of L-Tyrosine and L-Phenylalanine. The total dipoles of theses mixtures are given by absorption line shape function. Moreover, the statistical method of principle components analysis is employed to spectral recognition of these samples.
