Engineering a Rotating Sample Cell for Ultrafast Two-Dimensional Electronic Spectroscopy

Abstract

Two-dimensional electronic spectroscopy (2DES) is a collection of techniques that allow us to track energy and charge transfer by exciting pigments with lasers and tracking the frequencies emitted following a range of delay times. While working with the Ogilvie Group at the University of Michigan’s physics REU, I was tasked with developing a rotating sample cell to prevent the same area of sample from being targeted twice in a row. In this paper, I discuss the techniques and advantages of 2DES, the limitations that we still face which motivated my work, and the development of my Rotating Sample Cell.
