Vibrational Study of Melatonin and its Radioprotective Activity towards Hydroxyl Radical

摘要

Vibrational study of Melatonin (N‐acetyl 5‐methoxytrypatamin) was done using FTIR and Raman spectroscopy. DFT calculations were employed to the structural analysis of melatonin and to the end products. The theoretical calculations confirmed the different observed vibrational modes. The optimized structure energy calculations of the different end products confirmed the most probable site of the hydroxyl radical attack is the hydrogen attached to nitrogen present in the indole ring.
