Two-Dimensional Infrared Spectroscopy of Metal Carbonyls

Abstract: Metal carbonyl complexes offer both rich chemistry and complex vibrational spectroscopy due to strong coupling among the carbonyl stretches. Using two-dimensional infrared (2DIR) spectroscopy, it is possible to resolve the underlying transitions between vibrational energy levels, determine the orientations and relative magnitude of the corresponding transition dipole moments, measure the coupling between modes due to the anharmonicity of the potential, and probe energy redistribution among the modes as well as… Show more

“…However, the effect of ions on vibrational dynamics of a given molecule has begun to be investigated recently with an advent of time-resolved vibrational spectroscopic techniques such as ultrafast infrared-Raman, infrared pump-probe (IR PP), and two-dimensional IR (2DIR) experiments [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. A vibrationally excited molecule undergoes different relaxation processes on various timescales including vibrational energy transfer to anharmonically coupled vibrational modes [23,24], vibrational energy dissipation into the solvent [25], and resonance energy transfer to nearby vibrational modes with similar vibrational energies [26][27][28][29][30].…”

“…In particular, over the last 15 years, 2D-IR spectroscopy [1][2][3] has been successfully applied to studies of a range of structural dynamics [4,5] and energy transfer processes [6,7]. A wide range of approaches involve pulsed IR excitation and IR probing of samples providing detailed dynamical information about vibrational processes in molecules.…”

“…For instance, anharmonic couplings between collective normal modes can be studied in quite some detail using ultrafast two-dimensional IR spectroscopy. Taking metal-carbonyl compounds as an example, anharmonic couplings [1] and spectral diffusion [2] have been studied for Mn 2 (CO) 10 .…”
