title: Two-color delay dependent IR probing of torsional isomerization in a [AgL₁L₂]⁺ complex.
abstract: Two-color infrared multiple photon dissociation (2c-IR-MPD) spectroscopy with delayed pulses indicates a torsional isomerization in a "ligand-metal-chelate" complex [AgL1L2](+). Ab initio calculations reveal the torsional barrier as well as the change in vibrational frequencies and IR intensities along the isomerization pathway. The current approach bears prospects for further elucidation of competing interactions within naked or microsolvated complexes in gas phase coordination chemistry.
