text: This technique can identify weak points in polypropylene or aramid fibers as applied stress affects the fibers’ response to this technique.
full_question: This technique can identify weak points in polypropylene or aramid fibers as applied stress affects the fibers’ response to this technique. In a variant of this technique, a depolarization ratio greater than three-fourths shows that the sample has asymmetric vibrations. This technique penetrates deep beneath surfaces in its spatially offset variant. The results of this technique are characterized by the change in scattered photon energy and are known as Stokes and anti-Stokes shifts. For 10 points, name this technique used to probe low frequency molecular modes, named for an Indian physicist.
first_sentence: This technique can identify weak points in polypropylene or aramid fibers as applied stress affects the fibers’ response to this technique.
