A modified Landau-Teller equation for vibrational relaxation in the condensed phase is proposed. This equation differs from previous approaches by accounting for the fluctuations of the energies of the vibrational levels that result from the interactions with the surroundings (bath). In the conventional approach the effects of the bath are only included in the coupling between the relaxing and accepting vibrational modes. It is shown that the additional inclusion of the fluctuations of the energy levels can lead to a dramatic change of the vibrational relaxation rate.
提出了一种用于凝聚相中振动弛豫的修正朗道 - 特勒方程。该方程与先前的方法不同，它考虑了由于与周围环境（热库）相互作用而导致的振动能级能量的涨落。在传统方法中，热库的影响仅包含在弛豫振动模式和接受振动模式之间的耦合中。结果表明，额外考虑能级的涨落会导致振动弛豫速率发生显著变化。
