AI Article Synopsis
- Development of a subpicosecond spectropolarimeter enhances the detection of time-resolved circular dichroism (TRCD) in chiral solutions.
- The system utilizes a femtosecond pump-probe setup combined with a quarter-waveplate and a Wollaston prism for better sensitivity and shorter acquisition times.
- The study also covers potential artifacts in the detection method and demonstrates its effectiveness through research on [Ru(phen)]·2PF complexes in acetonitrile.
Article Abstract
Here we present the development of a subpicosecond spectropolarimeter enabling high sensitivity balanced detection of time-resolved circular dichroism (TRCD) signals from chiral sample in solution. The signals are measured with a conventional femtosecond pump-probe set-up using the combination of a quarter-waveplate and a Wollaston prism. This simple and robust method allows access to TRCD signals with improved signal-to-noise ratio and very short acquisition times. We provide a theoretical analysis of the artifacts of such detection geometry and the strategy to eliminate them. We illustrate the potential of this new detection with the study of the [Ru(phen)]·2PF complexes in acetonitrile.
