对于缩合相，压缩的基本作用是增加构成相的原子、离子或分子的外层电子之间的相互作用。由于不同类型的轨道具有不同的空间性质，它们受到这种增加的相互作用的不同程度的扰动。这种“压力调谐光谱”对于表征决定发光能量和效率的参数以及测试有关这些现象的理论是非常有效的。在本文中，我们讨论了一系列的例子，主要是从分子发光的研究中获得的，其中一个例子是离子固体，其结果是根据费德·威廉姆斯的理论来解释的。一些例子包括：1；(1)键压缩和范德华相互作用对分子荧光能量和效率的影响；(2)溶剂粘度对发光效率的影响；(3)|利用压力调节增强或抑制能量传递；(4)|利用压力调谐来测试理论的发光效率。
For condensed phases, the basic effect of compression is to increase interaction among the outer electrons of atoms, ions or molecules which constitute the phase. Since various types of orbitals have different spacial properties they are perturbed in different degrees by this increased interaction. This “pressure tuning spectroscopy” is very effective for characterizing the parameters which determine the energy and efficiency of luminescence and for testing theories concerning these phenomena.In this paper we discuss a series of examples taken largely from studies of molecular luminescence with one example of an ionic solid where the results are explained in terms of a theory due to Ferd Williams. Some of the examples include:1.(1)|the balance between bond compression and Van der Waals interactions in influencing molecular fluorescence energy and efficiency,2.(2)|the effect of solvent viscosity on luminescence efficiency,3.(3)|the use of pressure tuning to enhance or inhibit energy transfer,4.(4)|the use of pressure tuning to test theories of luminescence efficiency.
