Absorption spectra for Kr at 109 bar at various times after the pulse: 1 ns, ◆ ——; 5 ns - - - - -, ▲; and 9 ns ●——-.
(a) Pulse-probe experiment at 114 bar and 920 nm. Smooth line is fit to the data. (b) Simulated trace of excimer species at 114 bar.
Rate of formation of excimer B vs [Kr].
Rates of decay of B and growth of C vs Kr concentration.
Spectrum at 54 bar and 30 ns. Species C dominates, absorbing at 1065 nm.
Spectra of excimer transients at 15 bar. Solid circles at ; solid line is spline fit at that time. Open circles at ; dashed line is spline fit at that time.
Absorption trace of species A at 1300 nm and 109 bar. Fit shows two lifetimes 1.0 and 7.0 ns.
(a) 54 bar—species A absorbing at 790 nm. Lifetimes 1 and 23 ns. (b) Calculated concentration of excimer state vs time at 54 bar.
Calculated excimer concentration versus time at 54 bar. Solid line is , Dash-dash is , Dash-dot-dash is the fluorescent triplet and Dash-dot-dot-dash is the fluorescent singlet . The other species are all close to baseline.
Species lifetimes and time of peak maximum (nanosecond).
