Transition between the ground state and a state in which a single mode of vibration is multiply excited.
Note:
An overtone band results from an overtone transition.
An overtone band results from an overtone transition.
Example:
Transition from the ground state to the state in which \(\nu_{i} \ge 2\), \(\nu_{j \neq i} = 0\).
