Good quality polarized Raman spectra of a single wool fiber and an intact feather barbule are presented. The intensity ratio of the โฃ-helix component of the amide I band measured parallel and perpendicular to the wool fiber axis was 0.39 ฯฎ 0.05. This is consistent with theoretical predictions based

## Abstract Raman spectroscopy and tensile tests were used to investigate the structure transformation of stretched wool fibers with stretching ratios up to 110%. The typical bands analyzed in this article included the amide I region, the amide III region, the C๏ฃฟC skeletal vibration region, and the
