Fig. 2: Alignment traces of the N–N axis and Ar-axis for an isolated N2 molecule, Ar2 dimer, and N2–Ar dimer.
From: Intermolecular interactions probed by rotational dynamics in gas-phase clusters

Measured (horizontal step curves) and calculated (smooth curves) time-dependent alignment traces of N–N axis for a isolated N2 molecules and b N2–Ar dimers. c Measured (horizontal step curves) and calculated (smooth curves) time-dependent alignment traces of the Ar-axis of N2–Ar and Ar2 dimers. The shaded areas in (a–c) represent the standard deviations of three data sets.
