Abstract

A transient circular dichroism (CD)-based approach, called time-resolved circular dichroism (TRCD) spectroscopy, serves as an alternative to circularly polarized luminescence (CPL) spectroscopy for the investigation of excited-state chirality. The experimental apparatus for TRCD measurements was designed and is presented here. The Jones calculus approach to assessing experimental observables is also reported. Finally, to demonstrate the feasibility of TRCD, the CD spectrum of the photo-excited state of [6]carbohelicene is obtained.
