IV. NONELECTROMAGNETIC CONTRIBUTIONS TO SERS As successful as the em theory has been, there exists a number of observations that do not seem to be easily explicable in terms of it, which include, for example, the following. (1) The molecules CO and N2, whose Raman cross sections are almost identical, produce SERS spectra of rather different intensities (Moskovits and DiLella, 1982b).When coadsorbed in equal numbers onto cold-condensed silver films, CO produces a broad Raman peak shifted by some 28 cm- from that of unbonded CO, while N2 pro-duces a narrow Raman peak, shifted by only 2 cm-',whose intensity is about fifty times lower than that of CO. Suggestions that CO perhaps displaces N2 from the surface were countered with experiments in which N2 and CO were adsorbed independently with results similar to those in the coadsorption experiments. Likewise, postulating different surface bonding orientations for CO and N2, the former being "end-on" bonded, while the latter is sidewise bonded, cannot account for the full fiftyfold discrepancy. On the basis of the Raman depolarization ratios of the two molecules, at most a factor of 10 may be obtained for the ratio of the Raman intensities resulting from the adoption of the two orientations. Molecules such as methane and ethane produce SERS spectra some one-hundred-fold less intense than do ethylene or benzene, even though the ordinary Raman spectra of all of these molecules contain bands of equivalent strength. (2) In its simplest forms the em theory predicted that the SERS spectrum of a molecule should be a uniformly enhanced version of the ordinary Raman spectrum (McCall et al., 1980). Observations show this not to be true. This discrepancy is dramatically shown in the SERS spectrum of C6F6 (Fig. 24), which shows the C-F symmetric "breathing" vibration to be the dominant feature, while the same vibration is among the weakest in the ordinary Raman spectrum of the same molecule. Moreover, the SERS spectrum of many molecules (Erdheim et al., 1980; Dornhaus et al., 1980; Moskovits and DiLella, 1980,1982a,1982b) displays normally forbid-den features, often with intensities comparable to the most intense of the allowed transitions. (3)In SERS studies involving roughened electrodes immersed in aqueous electrolytes or aqueous metal colloids one does not observe a strong SERS spectrum of water, which presumably surrounds the SERS-active features in abundance. (4) It has also been observed that the SERS excitation spectrum obtained from aqueous colloidal silver does not correspond well with the absorption spectrum of the same colloid (Creighton et al., 1979; Mabuchi et al., 1982; Sii-man et al., 1983). The latter usually consists of a strong peak at about 390 nm with weaker features to the red of this. The 390-nm peak is associated with spherical colloidal particles, while the red peak or peaks are commonly believed to come about from aggregated colloid whose optical properties were discussed either in terms of ellipsoidal particles or by considering coupling between two or among several spheres. Although it is clear from the work of Aravind et al. (1981) that dipolar coupling is in-sufficient to account for the electrostatic fields about spheres spaced so closely together, dipolar coupling, often couched in the language of effective medium theories such as the Maxwell-Garnett theory does produce a red-shift plasmon peak whose exact position depends on the density of (hence average distance between) the colloidal spheres. 请翻译这段英文
IV. 非电磁贡献对SERS的影响 尽管电磁理论取得了成功,但仍存在一些观察结果似乎无法轻易通过电磁理论解释,例如: CO和N2分子的拉曼散射截面几乎相同,但它们产生的SERS光谱强度却大不相同(Moskovits和DiLella, 1982b)。当以相等数量共吸附在冷凝银膜上时,CO产生了一个宽的拉曼峰,偏移了约28 cm-1,而N2产生了一个窄的

有什么具体的现象能说明碎片化传播消解了传统文化整体性吗
碎片化传播通过微内容的形式,将中国传统文化的宏大、整体、系统性内容进行碎片化处理,以适应微空间的内容生产、传播习惯和读者的阅读习惯。这种现象导致传统文化在传播过程中不可避免地面临碎片化,弱化了其整体性与严肃性。数字技术重新定义了文化传播的时间效能,使文化传播的时效具备了即时性、碎片性和恒定性,进一步加剧了传统文化的碎片化传播。 在数字时代,高度信息碎片化和

杜瓦杰效应
杜瓦杰效应指的是由法国政治学者莫瑞斯·迪韦尔热(Maurice Duverger)在20世纪50年代提出的关于选举制度与政党体系之间关系的理论,即迪韦尔热定律。该定律认为,相对多数代表制倾向于产生两党制,而比例代表制则易导致多党制的形成。 😊杜瓦杰效应的主要内容 两党制倾向**:迪韦尔热定律指出,在相对多数代表制下,由于选举规则的“
早晨的红色天空意味着什么?
早晨的红色天空通常意味着大气中存在大量的气溶胶粒子,这些粒子能够散射红光。 🌅 红色天空的原因 光的散射:早晨太阳升起时,阳光穿过大气层,遇到气溶胶粒子,红光波长较长,穿透力强,因此被散射到天空中,形成红色天空。 🌦️ 天气条件 大气湿度:当大气中水分较多时,容易形成气溶胶,增加了光的散射效果,使得天空呈现红色。
