    "description": "The recently discovered vanadium-based Kagome metals AV\u2083Sb\u2085 (A = K, Rb, Cs) undergo a unique phase transition into charge-density wave (CDW) order which precedes both unconventional superconductivity and time-reversal symmetry breaking. Therefore the essential first step in building a full understanding of the role of CDW in establishing these unconventional phases is to unveil the symmetries and the microscopic nature of the charge-ordered phase. Here, we determine the exact structure of the 2\u00d72\u00d72 superlattice that develops below the charge-density wave ordering temperature (TCDW) in RbV\u2083Sb\u2085. We present a comprehensive set of \u2075\u00b9V, \u2078\u2077Rb, and \u00b9\u00b2\u00b9Sb nuclear magnetic resonance (NMR) measurements and density functional theory simulations of NMR observables to provide a unique site-selective view into the local nature of the charge-ordered phase. The combination of these experimental results with simulations provides compelling evidence that the CDW structure prevailing below 103 K in RbV\u2083Sb\u2085 is the so-called inverse Star of David pattern, \u03c0-shifted along the c axis. These findings put severe constraints on the topology of these Kagome compounds and thus provide essential guidance for the development of an appropriate theoretical framework for predicting properties of exotic electronic orders arising within the CDW phase.",
