英语翻译
At the atomic level,infrared energy elicits vibrational modes in a molecule through a change in the dipole moment ,making it a useful frequency range for study of these energy states for molecules of the proper symmetry.Infrared spectroscopy examines absorption and transmission of photons in the infrared energy range,based on their frequency and intensity.
