The behavior of near-field heat transfer between molecules at gaps which are small compared to wavelength of light is greatly influenced by non-radiative dipole-dipole interactions between the molecules. Here we derive the coupling parameters and estimate the near-field heat transfer between two molecules using coupled Drude oscillators. The predictions from this model are verified with results from standard fluctuational electrodynamics principles. The effect of orientation factor of the dipole moments in the molecules traditionally taken into consideration for analysis of resonance energy transfer between molecules but is hitherto overlooked for NFHT is also discussed.

用于模拟分子间近场传热的耦合参数

分子间的近场传热行为在与光的波长相比较小的间隙处受到分子间非辐射偶极-偶极相互作用的极大影响。在这里，我们导出耦合参数并使用耦合德鲁德振荡器估计两个分子之间的近场传热。该模型的预测得到了标准波动电动力学原理的结果的验证。还讨论了分子中偶极矩的取向因子的影响，传统上在分析分子之间的共振能量转移时考虑，但迄今为止在 NFHT 中被忽略。
