Question

Explain effect of hydrogen bond on intensity and position of IR band.​

Answer 1

Answer:

Hydrogen-bonding interactions lead to significant changes in the infrared (IR) spectrum, like frequency shifts of the order of magnitude of hundreds of cm–1 and increases of IR intensity for bands related to vibrational modes of functional groups directly involved in the hydrogen-bonded bridges.

Answer 2

Explanation:

Hydrogen-bonding interactions lead to significant changes in the infrared (IR) spectrum, like frequency shifts of the order of magnitude of hundreds of cm–1 and increases of IR intensity for bands related to vibrational modes of functional groups directly involved in the hydrogen-bonded bridges. We are actively developing a comprehensive and robust computational protocol aimed at the quantitative reproduction of the spectra of bio-organic and hybrid organic/inorganic molecular systems
