This study elucidates the information content that is extracted from action-2D electronic
spectroscopy (A-2DES) when the output intensity is not proportional to the number of …

Multidimensional optical spectroscopies are powerful techniques to investigate energy
transfer pathways in natural and artificial systems. Because of the high information content of …

In recent years, action-detected ultrafast spectroscopies have gained popularity offering
distinct advantages over their coherently detected counterparts, such as spatially resolved …

We present a nonlinear spectroelectrochemical technique to investigate photosynthetic
protein complexes. The PEC2DES setup combines photoelectrochemical detection (PEC) …

We demonstrate fluorescence-detected two-dimensional electronic spectroscopy (F-2DES)

Discerning the impact of the coherent motion of the nuclei on the timing and efficiency of
charge transfer at the donor–acceptor interface is essential for designing performance …

Action spectroscopies use a readout created by the action of light on the molecules or
material rather than optical absorption. Ultrafast 2D photocurrent and 2D fluorescence …

Calculation of nonlinear spectra of chromophore aggregates using response function theory
when the number of contributing chromophores is large, and the level of excitation is high is …

The size tunable color of colloidal semiconductor quantum dots (QDs) is probably the most
elegant illustration of the quantum confinement effect. As explained by the simple “particle …
