Sample Modulated Raman Spectroscopy and Frequency Modulated Visible Light: Resonance Raman Spectrum of a Polydiacetylene Fiber.

Abstract

Certain Raman-active vibrational modes of polydiacetylene fibers shift in frequency as they are stretched. Thus, the frequency of the Raman-scattered visible light itself shifts as the fiber sample is subjected to a tensile stress. In this work a fiber has been subjected to a periodic tensile stress, and the frequency of the Raman scattered light was found to be modulated at the frequency of this stress.
