Subpicosecond IR transient absorption spectroscopy: measurement of internal conversion rates in DABCO vapor
Abstract
An apparatus combining subpicosecond 248.5 nm pump pulses with a time-resolved subpicosecond broadband infrared absorption spectroscopy probe has been utilized to measure an internal conversion rate in 1,4-diazabicyclo[2.2.2]octane vapor. A subpicosecond ({less-than or approximate} 500 fs) internal conversion rate has been determined. © 1987.
