The linear response of the molecular aggregate chain with the random distribution of the strength of the neighboring intermolecular interactions to the bichromatic electromagnetic field has been calculated. The presence of the linearly polarized field produces additional resonance absorption at the combined frequencies of the circularly polarized and linear polarized field. The strength of the absorption oscillates with the amplitude and the frequency of the linearly polarized electromagnetic field. Additional resonance absorption is weaker than the main absorption at the frequency of the circularly polarized field. Similar behavior has been predicted for the interaction of the bichromatic magnetic field with the quantum spin-1/2 chain with the random distribution of the exchange constants for nearest neighbor spins.

双色电磁场对随机分子聚集体或量子自旋链的影响

已经计算了分子聚合链的线性响应以及相邻分子间相互作用强度的随机分布对双色电磁场的影响。线性极化场的存在在圆极化和线性极化场的组合频率下产生额外的共振吸收。吸收强度随线性极化电磁场的振幅和频率而波动。附加共振吸收比圆极化场频率处的主要吸收弱。对于双色磁场与量子自旋 1/2 链的相互作用以及最近邻自旋的交换常数的随机分布,已经预测了类似的行为。
