Figure 4: Population transfer from n=32.

Averaged transfer ratio from the initial p state to for n=32 with a transfer time of . The solid line at 6.61 V cm⁻¹ corresponds to the expected field for the three-body FRET. The dashed line at 6.36 V cm⁻¹ marks the resonance electric field of the 4² four-body FRET where two relay atoms allow the energy exchange between the last two atoms. The dotted line at 6.14 V cm⁻¹ corresponds to the 5³ five-body FRET allowed through three relay atoms. Finally, the dashed-dotted line at 6.74 V cm⁻¹ corresponds to the 5¹ five-body FRET where a single relay atom is enough to allow the energy exchange of two pairs of atoms. Each point corresponds to the average of 150–300 individual measurements. The error bars correspond to the sum of the s. e. m. and the estimated error in the state discrimination.
