In molecular vibrational spectroscopy, a hot band is a band centred on a hot transition, which is a transition between two excited vibrational states, i.e. neither is the overall ground state. In infrared or Raman spectroscopy, hot bands refer to those transitions for a particular vibrational mode which arise from a state containing thermal population of another vibrational mode. For example, for a molecule with 3 normal modes, , and , the transition ← , would be a hot band, since the initial state h… WebNormal infrared absorption occurs between the v = 0 and v = 1 levels. The v = 0 to v = 2, etc. transitions are called overtones. They are forbidden transitions, thus have smaller peaks. The v = 1 to v = 2 transition is called a hot band. It occurs because thermal energy populates v = 2 to some small extent. As the temperature is
