摘      要：CO_(2) capture is considered as one of the most ideal strategies for solving the environmental issues and against global ***,experimental evidence has suggested that aluminum double bond(dialumene) species can capture CO_(2) and further convert it into value-added ***,the catalytic application of these species is still in its *** the dynamics mechanism of CO_(2) fixation and the detailed structures of catalytic intermediates are not well *** this work,we investigate the structure dependent resonance Raman(RR) signals for different reaction ***-initio simulations of spontaneous resonance Raman(spRR) and time-domain stimulated resonance Raman(stRR) give spectral signatures correlated to the existence of different intermediates during the CO_(2)-dialumene binding *** unique Raman vibronic feature s contain rich structural information with high temporal resolution,enabling to monitor the transient catalytic intermediates under reaction *** work shows that RR can be used to monitor intermediates during the dialumene based CO_(2) capture *** spectral features not only provide insight into the structural information of intermediate species,but also allow a deeper understanding of the dynamical details of this kind of catalytic process.
