The light-induced spin and structure changes upon excitation of the singlet metal-to-ligand
charge transfer (1MLCT) state of Fe (II)-polypyridine complexes are investigated in detail in …

The ultrafast spectroscopic investigation of novel retinal proteins challenges existing notions
concerning the course of primary events in these natural photoreceptors. We review two …

Iron (II)-based molecular complexes have been a subject of intense study since the
discovery of light-induced excitedstate spin trapping (LIESST).[1] In this process, excitation …

This perspective presents some recent results concerning ultrafast intramolecular relaxation
processes in metal-based molecular complexes. Ultrafast electronic/vibrational relaxation at …

Femtosecond fluorescence up-conversion, UV-Vis and IR transient absorption spectroscopy

We investigate the ultrafast transient absorption response of tetrakis (μ-pyrophosphito)
diplatinate (II),[Pt2 (μ-P2O5H2) 4] 4−[hereafter abbreviated Pt (pop)], in acetonitrile upon …

Channelrhodopsins are light-gated ion channels with extensive applications in
optogenetics. Channelrhodopsin-1 from Chlamydomonas augustae (Ca ChR1) exhibits a …

Photochemistry in retinal proteins (RPs) is determined both by the properties of the retinal
chromophore and by its interactions with the surrounding protein. The initial retinal …

We report the results of ultrafast transient absorption studies of tetrakis (μ-pyrophosphito)
diplatinate (II),[Pt 2 (μ-P 2 O 5 H 2) 4] 4−(Pt (pop)) and its perfluoroborated derivative [Pt 2 (μ …

The coherent photoisomerization of a chromophore in condensed phase is a rare process in
which light energy is funneled into specific molecular vibrations during electronic relaxation …
