激光波长对杂散光及信噪比的影响十分显著,当狭缝宽度不变时,用氩激光514.5nm比用488.0nm波长激发样品,杂散光要小一到二个数量级(±100cm-1范围内),并且分辨率有所提高。
并且随激发波长的增长,蓝移减小。
The blue shift is reduced with increase of exciting wavelength.
另外,外电场对TCNQ分子的激发波长也产生了一定影响。
Other, the electric fields have some effect on the wavelengths of TCNQ.
结果表明:含荧光基团的共聚物的激发波长与发射波长基本与荧光单体相同。
The results showed that the excited and the emitted wavelength of the copolymers containing fluorescent monomer were the same as those of the monomers respectively.
