DYNAMIC FT-IR SPECTROSCOPIC STUDIES OF SILK FIBROIN FILMS

Dynamic FT-LR spectra in the amide I region were measured for silk fib roin east films, Phase analyses of the dynamic spectra were carried ou t in order to separate them into several components which are due to t he secondary structures of fibroin. These observations showed that pea k positions of the amide I bands were in good agreement with those obt ained by Fourier self-deconvolution procedures, In conclusion, phase a nalysis of dynamic FT-IR spectra is a powerful technique for separatio n of highly overlapping bands.
