“…with equal pump and probe frequencies) is a peak corresponding to the bleach (and stimulated emission) of the v = 0-1 transition of the excited mode (1). This is accompanied by a peak of the opposite sign attributable to the v = 1-2 excited state absorption feature, arising from population of the v = 1 state by the pump pulse (2). This feature appears at the same pump frequency as the diagonal peak but is shifted to lower probe frequencies due to the anharmonicity of the excited mode.…”

“…This provides useful insight into the time spent by radicals within the solvent cage following photodissociation, though it is also the case that the trans form was found to be the most thermodynamically-stable species under equilibrium conditions and the recombination time of ~30 ps will be comparable to the 10 | J. Name., 2012, 00, [1][2][3] This journal is © The Royal Society of Chemistry 2012 rotation time of the species formed. It is however interesting that no gauche isomer recovery was noted and raises the possibility that a role exists for the solvent in controlling the photochemical reaction coordinate.…”

“…The introduction of time-resolved spectroscopy methods, employing an IR probe of an electronically-excited system, opened up further possibilities for following photochemical processes or dynamics associated with, or subsequent to, excitation. [1][2][3][4][5][6][7][8][9][10] Implementation of these techniques has progressed in line with laser technology development to the extent that spectrometers with high time resolution (~50 fs) and broad spectral bandwidths (>300 cm -1 ) are readily achievable using commercially-available bench-top laser systems. As chemical research in the inorganic sector advances and the molecules become more complex, the need arises to understand, and so eventually control, their excited state chemistry and dynamics at ever more nuanced levels.…”

The Strathprints institutional repository (https://strathprints.strath.ac.uk) is a digital archive of University of Strathclyde research outputs. It has been developed to disseminate open access research outputs, expose data about those outputs, and enable the management and persistent access to Strathclyde's intellectual output.Journal Name Time-resolved infrared spectroscopy has been proven to be a powerful tool for investigating the structure, dynamics and reactivity of electronically-excited states of inorganic molecules. As applications drive the production of ever more complex molecules however, experimental tools that can deliver more detailed spectroscopic information, or separate multiple contributions to complex signals will become increasingly valuable. In this Perspective, the extension of ultrafast infrared spectroscopy of inorganic excited states to a second frequency dimension using transient 2D-IR spectroscopy (T-2D-IR) methods is discussed. Following a brief discussion of the experimental methodologies, examples will be given of applications of T-2D-IR ranging from studies of the spectroscopy, structure and dynamics of photochemical intermediates to new tools for correlating vibrational modes in ground and excited electronic states and the investigation of excited state solvation dynamics. Future directions for these experiments are also discussed.

“…We have therefore designed a ligand system based on pyrrolide anions containing an additional hemilabile π unit 6c. In fact, the pyrrolide anions are isoelectronic with the cyclopentadienyl anions that have produced a number of dinitrogen complexes,1c,d,e,h,m,l,p, 13 including examples that facilitate dinitrogen reduction 1c,d,e,h,m,l,p. By reducing a trivalent titanium complex of the 2,5‐{(C 4 H 3 N)CPh 2 } 2 C 4 H 2 N(Me) dianion, we recently obtained a toluene mixed‐valence complex with inverted sandwich structure, which is an example of olefin coordination 14.…”
