WebbThe near-field Raman band at 739 cm−1 (Band H) is assigned to a ring-breathing mode of whole adenine molecules. The band at 1328 cm −1 (Band B) is assigned to a summation of two different vibrational modes. The first mode involves the C 5 -N 7 and N 1 -C 2 symmetric stretching coupled with the C 2 -H and C 8 -H symmetric in-plane bend. Webb12 juli 2024 · Driven by applications in chemical sensing, biological imaging and material characterisation, Raman spectroscopies are attracting growing interest from a variety of scientific disciplines. The Raman effect originates from the inelastic scattering of light, and it can directly probe vibration/rotational-vibration states in molecules and materials. …

WebbSince Rayleigh and Raman scattering are observed quite readily with very much lower electric field intensities, one may expect to explain Rayleigh and Raman scattering in terms of μ (1) only. We shall now consider the interaction of a molecular system with the harmonically oscillating electric field in the frequency ω 0 .
