What Is Vibrational Fine Structure? The vibrational states of a molecule can be probed in a variety of ways. … The combined excitation is known as a vibronic transition, giving vibrational fine structure to electronic transitions, particularly for molecules in the gas state. What is meant by vibrational mode? A mode of vibration can be

What Conditions Must Be Satisfied For A Vibrational Mode To Be IR Active? What condition needs to be satisfied for a vibrational mode to be IR-active? It must be associated with changes in dipole moment. How do you know which vibrational modes are IR active? In order to determine which modes are IR active, a
