Electronically induced IR multiphoton absorption: a direct probe of the quasicontinuum

Electronic excitation followed by nonradiative decay provides a novel method for directly accessing the vibrational quasicontinuum of polyatomic molecules. From there efficient nonresonant absorption of infrared photons occurs. Quasi-continuum CrO 2Cl 2 molecules absorb off-resonance radiation with...

Description
Summary:Electronic excitation followed by nonradiative decay provides a novel method for directly accessing the vibrational quasicontinuum of polyatomic molecules. From there efficient nonresonant absorption of infrared photons occurs. Quasi-continuum CrO 2Cl 2 molecules absorb off-resonance radiation with near-resonance efficiency. Some fluence threshold effects persist when absorption originates from the quasicontinuum.
