title: Measurement data for the hyperfine splitting and the lifetime of the 2F_7/2 clock state in 173Yb+        
description:     This file includes the measurement data that supports our finding for the paper “Nuclear spin quenching of the 2𝑆1/2→2𝐹7/2 electric octupole transition in 173Yb+”, DOI https://doi.org/10.1103/fx1b-5666.  
The finding includes the measured frequencies and hyperfine splittings of the 2𝑆1/2→2𝐹7/2 electric octupole transition in 173Yb+.  
In addition, the Rabi frequencies of several clock transitions are measured, that is related to the strength of the hyperfine induced electric dipole decay channel, which is caused by the large nuclear deformation of 173Yb+ and its nuclear spin of I=5/2.
