Which of the following statements about IR spectroscopy are true? Check all that apply. The frequency of vibration depends on the mass of the atoms on either end of the excited bond. A common light source used to generate light of IR wavelengths is a tungsten filament lamp. The type of bond (single, double, triple) has no effect on the energy required for excitation in IR spectroscopy. The potential energy of bond oscillation is affected by Coulombic repulsion when the...
