Web12 de set. de 2024 · The energy of a wave is proportional to the square of the amplitude, which is related to the number of photons. So certainly it is correct to say that a photon of higher frequency has higher energy. Why does an amplitude wave transmit more energy? The other factor is frequency. WebNH stretch is the highest wave number absorption. This is a polar bond so strongly absorbs in IR and weakly in Raman. CH stretch is a doublet below 3000cm-1 (asymmetric and symmetric) which is less polar than NH and has a strong absorption in Raman but a weaker absorption in IR.

WebThe Raman shift for the vibration in H2 is observed way out past 4000 wavenumbers. In I2, it is observed from 100-200 wavenumbers. (I can't remember the exact shift for either of these, obviously there is only one number for each) A huge difference. So, the symmetric stretch probably vibrates at a higher frequency than the asymmetric stretch.
