项目摘要

As for the magnetic field effect of water, we have been observing the change in the optical properties of water under the high magnetic field. The field increased the refractive indices of water and shifted the optical absorption wavelength in the near infrared region. Those effects are assumed by the magnetic stabilization of the hydrogen bonding. At the time, we also pointed out that the refractive index of the adsorbed water on the gold surface might be much sensitive than those in the bulk, which. suggests these surface effects.. The evanescent mirror of SPR (surface plasmon. resonance) is controlled. electrochemically in dilute sulfuric acid aqueous solution. Under the careful electrochemical conditioning combined with the detection of the refractive index by SPR, the gold surface can set the native clean surface, that covered with sulfate ions and the gold oxide. The changes in the refractive indices between OT and 10T were on gold oxide < on sulfate adsorption < on clean gold. When the gold surface was capped by dodecane-thiol or oxide, the refractive index change was identical to that of the bulk. In considering the amount of the trapped water is one or two molecular layers and the evanescent wave samples more than 1000 water in the bulk, the obtained surface effect is tremendous than that of the bulk. As for the magnetic field effect of the electrochemical processing of the molecular wire, we have succeeded the direct observation of the polymerization of thiophene on Au(111). The molecular alignment of origo-thiopphene was affected by the magnetic field. This result was harmonized the observation that the wire moves on the surface by the agitation of the thermal fluctuation under 0T.

至于水的磁场效应，我们一直在观察水在强磁场下光学性质的变化。电场增加了水的折射率，并在近红外区域移动了光吸收波长。这些效应是由氢键的磁稳定性假设的。同时，我们还指出，吸附在金表面上的水的折射率可能比体相中的水的折射率敏感得多。表明这些表面效应。表面等离子体激元（SPR）的倏逝镜。共振）被控制。在稀硫酸水溶液中进行电化学反应。在仔细的电化学调节结合SPR检测折射率的情况下，金表面可以设置原生清洁表面，其覆盖有硫酸根离子和金氧化物。OT和10T之间的折射率变化为氧化金<硫酸盐吸附<清洁金。当金表面被十二烷硫醇或氧化物覆盖时，折射率变化与本体的折射率变化相同。考虑到被捕获的水的量是一个或两个分子层和倏逝波样品中的水超过1000块，所获得的表面效应是巨大的比体。对于分子线电化学加工的磁场效应，我们成功地直接观察到噻吩在Au（111）表面的聚合反应。磁场对噻吩分子的排列有一定的影响。这一结果与在0 T下通过热波动的搅动而在表面上移动的线的观察一致。
