Solvent-dependent intra- and intermolecular vibrational energy transfer of W(CO)6 probed with sub-picosecond time-resolved infrared spectroscopy

Ultrafast vibrational dynamics and solvation complexes of methyl acetate in methanol studied by sub‐picosecond infrared spectroscopy

“…Hamaguchi and coworkers have studied the solvent and the ligand dependences of the VER process of tungsten carbonyl complexes by IR pumpprobe spectroscopy. 15,16 In a series of IR pump-probe spectroscopic studies, we investigated the VER processes of the CO stretching modes of acetic acid in D 2 O 17 and 9-fluorenone (FL) in methanol. 18 When carbonyl compounds are dissolved into a protic solvent, intermolecular hydrogen bonds are formed between the oxygen atom of the carbonyl group and the hydroxyl group of the solvent molecules.…”

Ultrafast vibrational spectroscopy and relaxation in polyatomic molecules: Potential for molecular parallel computing

“…For example, for the pumping of W(CO) 6 to a state with one quantum of vibrational excitation (of the T 1u mode [9]) with a pump polarized in the x direction, we have four probe signals available, the transient absorptions signals in the x and the y directions of the ground state and of the v = 1 T 1u mode. The suitability of metal carbonyls for photophysical studies has been demonstrated in a number of previous studies [8][9][10][11].…”

“…Even at a high level of excitation it is still possible to assign states that are distinguishable via preparation by a short laser pulse [6]. Here we discuss a specific mid-infrared pump-probe experiment that prepares and interrogates vibrational states in metal carbonyls in solution [8][9][10][11]. The IR bright states are CO stretch motions.…”

Investigation of organometallic reaction mechanisms with one and two dimensional vibrational spectroscopy

“…There are only a handful of examples of fast vibrational energy transfer between the carbonyl vibrations of organometallic complexes in the literature [194,230,244,254,[257][258][259]. A rigorously documented example is Rh(CO) 2 (acac) (RDC; acac = C 5 H 7 O 2 ) which has been studied with ultrafast spectroscopy by several groups [194,230,244,259].…”
