| 中文摘要 | In order to investigate a noise-like signal appearing in dynamic mode measurement during laser flash photolysis experiments, five compounds were chosen which show this abnormal phenomenon. The reproducibility of this phenomenon was done repeatedly, indicating that it originates from each molecular structural property. Also their two regulation pattern or features were found by our analysis. One is a U-shaped curve of main frequency intensity with time and it seems to be directly related to the concentration of the T-1 excited state. The other is a high damping oscillation curve of the frequency shift with time and this curve seems to be indicating an energy transportation process from light into chemical energy. Finally, a possible origin of hydrogen nuclear optical resonance was proposed for the abnormal signal. (C) 2013 Elsevier B.V. All rights reserved. |
