Abstract

By expressing the fluctuation-dissipation theorem explicitly, equations are obtained for the ultrasonic relaxation amplitudes that contain one single molecular parameter, i.e., the fluctuation, or the sum of fluctuations. The absolute measurement of this parameter is therefore possible. The equations apply to a two-state system, to a multistate system and to a linear Ising chain as well. In an aqueous medium, where molar volume changes are important, the ultrasonic relaxation amplitudes are proportional to the volume fluctuations. For assemblies of biomolecules that exhibit enhanced ultrasonic absorption on assembly it is possible to measure the increase on assembly of the sum of fluctuations. In view of application to tobacco mosaic virus protein aggregates, examples are given in which the fluctuations associated with two normal modes of relaxation are equally enhanced when the difference of conformational stability of the states is reduced. The corresponding observable changes of the ultrasonic spectra are described.

摘要

通过明确表达涨落耗散定理，得到了包含单个分子参数（即涨落或涨落之和）的超声弛豫振幅方程。因此，对该参数进行绝对测量是可能的。这些方程同样适用于二态系统、多态系统以及线性伊辛链。在水介质中，摩尔体积变化很重要，超声弛豫振幅与体积涨落成正比。对于在组装时表现出增强超声吸收的生物分子聚集体，可以测量组装时涨落之和的增加量。鉴于其在烟草花叶病毒蛋白聚集体中的应用，给出了一些例子，其中当状态的构象稳定性差异减小时，与两种正常弛豫模式相关的涨落会同等增强。描述了超声光谱相应的可观测变化。
