Here we present an 17O NMR study of DQVOF, which isolates the local susceptibility of the breathing kagome network. By a fit to series expansion, we extract the ratio of the interactions within the breathing kagome plane, J∇/JΔ=0.55(4), and the mean antiferromagnetic interaction ¯¯¯J=60(7)  K. Spin lattice (T1) measurements reveal an essentially gapless excitation spectrum with a maximum gap Δ/¯¯¯J=0.007(7). Our study provides new impetus for further theoretical investigations in order to establish whether the gapless spin liquid behavior displayed by DQVOF is intrinsic to its breathing kagome lattice or whether it is due to perturbations to this model, such as a residual coupling of the V4+ ions in the breathing kagome planes to the interlayer V3+ (S=1) spins.",

By a fit to series expansion, we extract the ratio of the interactions within the breathing kagome plane, J∇/JΔ=0.55(4), and the mean antiferromagnetic interaction ¯¯¯J=60(7)  K.
