Abstract
In this review, the comprehensive summary of two-dimensional correlation spectroscopy (2D-COS) for the last two years is covered. The remarkable applications of 2D-COS in diverse fields using many types of probes and perturbations for the last two years are highlighted. IR spectroscopy is still the most popular probe in 2D-COS during the last two years. Applications in fluorescence and Raman spectroscopy are also very popularly used. In the external perturbations applied in 2D-COS, variations in concentration, pH, and relative compositions are dramatically increased during the last two years. Temperature is still the most used effect, but it is slightly decreased compared to two years ago. 2D-COS has been applied to diverse systems, such as environments, natural products, polymers, food, proteins and peptides, solutions, mixtures, nano materials, pharmaceuticals, and others. Especially, biological and environmental applications have significantly emerged. This survey review paper shows that 2D-COS is an actively evolving and expanding field.

Abstract
In this paper, the photophysical behavior of four panchromatically absorbing, homoleptic bis(4H-imidazolato)CuI complexes, with a systematic variation in the electron-withdrawing properties of the imidazolate ligand, were studied by wavelength-dependent time-resolved femtosecond transient absorption spectroscopy. Excitation at 400, 480, and 630 nm populates metal-to-ligand charge transfer, intraligand charge transfer, and mixed-character singlet states. The pump wavelength-dependent transient absorption data were analyzed by a recently established 2D correlation approach. Data analysis revealed that all excitation conditions yield similar excited-state dynamics. Key to the excited-state relaxation is fast, sub-picosecond pseudo-Jahn-Teller distortion, which is accompanied by the relocalization of electron density onto a single ligand from the initially delocalized state at Franck-Condon geometry. Subsequent intersystem crossing to the triplet manifold is followed by a sub-100 ps decay to the ground state. The fast, nonradiative decay is rationalized by the low triplet-state energy as found by DFT calculations, which suggest perspective treatment at the strong coupling limit of the energy gap law.

Abstract
![]()
Herein, we present
KiMoPack, an analysis tool for the kinetic modeling of transient spectroscopic data. KiMoPack
enables a state-of-the-art analysis routine including data preprocessing
and standard fitting (global analysis), as well as fitting of complex
(target) kinetic models, interactive viewing of (fit) results, and
multiexperiment analysis via user accessible functions and a graphical
user interface (GUI) enhanced interface. To facilitate its use, this
paper guides the user through typical operations covering a wide range
of analysis tasks, establishes a typical workflow and is bridging
the gap between ease of use for less experienced users and introducing
the advanced interfaces for experienced users. KiMoPack is open source
and provides a comprehensive front-end for preprocessing, fitting
and plotting of 2-dimensional data that simplifies the access to a
powerful python-based data-processing system
and forms the foundation for a well documented, reliable, and reproducible
data analysis.
