利用偏振敏感的多重相干反斯托克斯拉曼散射（ps-MCARS）技术，对高发光的八乙基卟啉锌（Zn-OEP）的振动光谱进行了研究。我们在这里表明，ps-MCARS可以用来测量共振条件下的振动带。偏振敏感汽车进一步有助于解决复合和重叠的拉曼带的振动对称性的变化的基础上。本文还阐明了多重汽车（MCARS）光谱的优点进行紧聚焦条件下提出的。我们证明了显微汽车聚焦和收集系统与多重技术相结合，可以减少样品量和缩短测量时间。我们分析了Zn-OEP骨架模不同振动带的对称性与相干振动相位之间的关系。对于具有相同对称性的振动带，相干振动相位的值是相似的。
Polarization-sensitive, multiplex coherent anti-Stokes Raman scattering (ps-MCARS) has been used to detect the vibrational bands of the highly luminescent zinc(II)-octaethylporphyrin (Zn-OEP). We show here that ps-MCARS can be used to measure the vibrational bands under resonant conditions. Polarization-sensitive CARS further helps to resolve composite and overlapping Raman bands on the basis of variations in vibrational symmetry. This paper also exemplifies the advantages of multiplex CARS (MCARS) spectroscopy carried out under tight focusing conditions as proposed earlier. We demonstrate that a microscopic CARS focusing and collection system in combination with the multiplex technique allows a reduction in the amount of sample and a shortening of the measurement time. We analyse the relationship between the coherent vibrational phases and the symmetry of the different vibrational band of Zn-OEP skeletal modes. The values of the coherent vibrational phases are similar for vibrational bands with the same symmetry.
