Such use of resonance effects for the purpose of characterization of an elastic object (shape, size, composition, and integrity) is similar to the way chemical elements are identified from their optical properties.

Principles of Artificial Colouring,evel. The Raman spectrum can be analyzed in terms of the molecular components or functional groups thus providing a “fingerprint” of the molecule. The Raman effect was first observed in 1928 by C.V. Raman and K.S. Krishnan , but wide application was delayed until the development of the laser. ThePeak-Bone-Mass 发表于 2025-3-26 18:16:19
