TRPES Investigation of Methylated Cyclopentadiene with UV Pump and XUV Probe

POSTER

Abstract

We have applied time-resolved photoelectron spectroscopy (TRPES) using two UV-pump wavelengths (266 nm and 252 nm) along with a 30-eV XUV probe to study the ultrafast dynamics and possible ring conversion of methylated cyclopentadiene (CPD). Using an XUV pulse as the probe provides access to the molecular dynamics beyond the Frank-Condon region. Our preliminary analysis shows different de-excitation timescales for tetramethyl-CPD and pentamethyl-CPD as well as a dependence on the excitation wavelength.
