论文摘要
已经研究了通过热振动红外辐射的发射分子和簇冷却的激发能的时间。能量分布和光子排放速率发展为几乎通用的函数，这些函数只能以少数参数为特征，而与系统的精确振动光谱和振荡器强度无关。光子发射常数和发射功率在所有热个子群的状态下平均，随着总激发能的偏移较小，偏移量均有线性变化。集合内部能量分布的时间发展是根据其前两个时刻计算的。对于发射速率常数的线性依赖性，这些结果是精确的。
The time development of the excitation energy of molecules and clusters cooling by emission of thermal vibrational infrared radiation has been studied. The energy distributions and the photon emission rates develop into near-universal functions that can be characterized with only a few parameters, irrespective of the precise vibrational spectra and oscillator strengths of the systems. The photon emission constant and emitted power averaged over all thermally populated states vary linearly with total excitation energy with a small offset. The time developments of ensemble internal energy distributions are calculated with respect to their first two moments. For the derived linear dependence of the emission rate constant, these results are exact.
