48、cule with n atoms has 3n-6 vibrational modes (3n-5 if linear): normal modes of vibration l事实上,不需要任何关于正则振动方式及 其频率的具体知识,就可以确定一个分子 正则振动的类型和频率的数目,这些结果 对于确定分子可能有哪些振动光谱是非常 重要的。 l我们知道,只有对称操作作用下,没有交 换位...
3N - 6 normal modes of vibration. There are several types of motion that contribute to the normal modes. Some examples are: • stretching motion between two bonded atoms; • bending motion between three atoms connected by two bonds; • out-of-plan deformation modes that change an...
These modes of vibration (normal modes) give rise to • absorption bands (IR) if the sample is irradiated with polychromatic light of suitable wavelengths upon changes of the dipole moment μ =α ·E + β ·E 2 +… • scattered light ...
The samples were fabricated by solid-state pressureless consolidation of nanopowders produced by laser ablation of solid target in air flow. In particular, we studied the influence of Sc3+ content on the active vibration modes in terms of peak positions and shifts, linewidths and shapes: these ...

[Sun, C. Q. Prog. Mater. Sci. 2009, 54, 179] of the measurements revealed that the thermally softened ZnO Raman modes arise from bond expansion and bond weakening due to vibration and that the pressure-stiffened Raman modes result from bond compression and bond strengthening due to ...
