Query: Molecular structure retrieval directly from laboratory-frame
  photoelectron spectra in laser-induced electron diffraction   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 laser-induced 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
quantum-classical calculations.
