Technique | Advantages | Disadvantages |
---|---|---|
Visible transient absorption (TA) | Information about excited state dynamics such as internal conversion, ISC and so on. Simple setup. | Blurred signals due to broadening. Mandatory requirement of optically allowed electronic transition. |
Time-resolved vibrational spectroscopy (IR) | Information about molecular vibrations at excited state. | Mandatory requirement of symmetry allowed vibrational modes. Challenging to set up. Costly lasers and detectors. |
Time-resolved X-ray diffraction | Information about molecular structural changes at excited state. High temporal and spatial resolution. | Requirement of specially prepared samples. Potentially sample damage by radiation. Complexity and synchrotron radiation facilities are usually required. |
2D spectroscopy | Enhanced resolution for signals mixed due to inhomogeneous broadening, compared to TA technique. Direct inspection of correlated state. | Long data acquisition time, stable samples required. Challenging to set up. |
Transient Raman | Information about molecular vibrations and conformational changes. | Weak signal. Interfered by fluorescence signal. |
Time-resolved photoluminescence | Wide range of detection time delay. Simple setup. | Mandatory requirement of detectable photoluminescence of the sample. Inferior time resolution. |
