CRASY: Correlated rotational alignment spectroscopy reveals atomic scrambling in ionic states of butadiene

Abstract

We use correlated rotational alignment spectroscopy to reveal atomic scrambling in transient ionic states of butadiene. Investigating a natural sample, we assign signals of two trans-1,3-butadiene isotopologues that contain a single 13C isotope and quantify the fragment abundance for the 13CH3 loss channel for each isotopologue.
