Subpicosecond OH production from photoexcited CO2-HI complexes

The subpicosecond resolution pump–probe method is used to obtain rates for OH production from CO2–HI complexes photoexcited in the HI ultraviolet continuum. Production lifetimes between 300 and 600 fs are reported for wavelengths between 255 and 235 nm, respectively. These lifetimes are close to the...

Zusammenfassung:The subpicosecond resolution pump–probe method is used to obtain rates for OH production from CO2–HI complexes photoexcited in the HI ultraviolet continuum. Production lifetimes between 300 and 600 fs are reported for wavelengths between 255 and 235 nm, respectively. These lifetimes are close to the RRKM predictions of HOCO° unimolecular decomposition under single collision conditions.
