Vibrational energy redistribution and vibrational dynamics of methanol mixed with Rhodamine 101 dye Xiaosong Liu Wei Zhang Weilong Liu Yunfei Song Zhuo Wang Wenjing Zhang 10.6084/m9.figshare.11481252.v1 https://tandf.figshare.com/articles/journal_contribution/Vibrational_energy_redistribution_and_vibrational_dynamics_of_methanol_mixed_with_Rhodamine_101_dye/11481252 <p>Vibrational energy transfer that occurs after photoexcitation can be tracked in the first several femtoseconds by ultrafast time- and frequency-resolved CARS (coherent anti-Stokes Raman scattering) spectroscopy. Vibrational energy transfer from high-frequency modes to lower ones through chemical bond of pure methanol and methanol/Rhodamine 101 (Rh101) solution is detected. Through comparison and analysis of the experimental results, it is found that surrounding molecules have a significant influence on vibrational energy transfer and vibrational couplings among relevant modes.</p> 2019-12-31 06:44:59 Vibrational energy transfer CARS vibrational couplings intermolecular interaction
