CCD-based
Pump-Probe Excitation and Detection System for recording
time-resolved absorption spectra
TAPPS
is a complete pump/probe transient absorption system designed
to assist scientists in understanding the deactivation dynamics
of excited states. Applications of this spectroscopic technique
extend from the fundamental studies of energy and electron
transfer processes in physics, chemistry and biology to the
design of logic gates in molecular electronics.
