相干二维共振拉曼光谱是一种多维技术，能够分离和分选在常规一维光谱中出现严重拥挤和无序的峰。它可以根据旋转和振动量子数、振动序列和旋转选择规则对旋转振动峰进行排序。新的结果表明，模式识别方法也可以用来确定高度详细的旋转振动信息是来自基态电子还是激发态电子。使用i2和C2的实验结果证明了这种能力。
Coherent 2D resonance Raman spectroscopy is a multidimensional technique that is capable of separating and sorting peaks that appear heavily congested and disordered in conventional 1D spectra. It can sort rovibrational peaks according to rotational and vibrational quantum number, vibrational sequence, and rotational selection rule. New results suggest that pattern recognition methods can also be used to determine whether the highly detailed rovibrational information is coming from the ground electronic state or the excited electronic state. This capability is demonstrated using experimental results from I2and C2.
