Abstract
Imaging the charge distributions and structures of molecules and clusters will promote the understanding of the dynamics of the quantum system. Here, we report a method by using an Ar atom as a tip to probe the charge distributions of benzene (Bz) cations in gas phase. Remarkably, the measured charge distributions of Bz+ (δ
H = 0.204, δ
C = −0.037) and Bz2+ (δ
H = 0.248, δ
C = 0.0853) agree well with the calculated Mulliken distributions, and the structures of Bz2 is reconstructed by using the measured charge distributions. The structures of two Bz2 isomers (T-shaped and PD isomers) can be resolved from the measured inter-molecular potential V(R) between two Bz ions, and the structures of Bz dimer agree well with the theoretical predictions.
