Abstract
Ubiquitous to most molecular scattering methods is the challenge to retrieve bond distance
and angle from the scattering signals since this requires convergence of pattern matching
algorithms or fitting methods. This problem is typically exacerbated when imaging larger
molecules or for dynamic systems with little a priori knowledge. Here, we employ laserinduced electron diffraction (LIED) which is a powerful means to determine the precise
atomic configuration of an isolated gas-phase molecule with picometre spatial and attosecond temporal precision. We introduce a simple molecular retrieval method, which is based
only on the identification of critical points in the oscillating molecular interference scattering
signal that is extracted directly from the laboratory-frame photoelectron spectrum. The
method is compared with a Fourier-based retrieval method, and we show that both methods
correctly retrieve the asymmetrically stretched and bent field-dressed configuration of the
asymmetric top molecule carbonyl sulfide (OCS), which is confirmed by our quantumclassical calculations.
