✦ Synopsis

A simple two-state model 1s apphed to estimate the nonlocal contnbutlon to the Frenkel state polanzablhty, resulting from the couphng of that state with charge transfer excltons The results suggest that m the S1 state of anthracene and tetracene the polarlzablhty may be dommated by nonlocal terms An explanation of the large dtscrepancles between the polanzablhtles measured in slightly different expenmental condltlons IS offered

## Abstract A comparison of experimental and theoretical values for Δα = Ξ±~__e__~ ‐ Ξ±~__g__~, assuming no sigma‐electron contribution, shows a great distortion by π‐electron calculations. We analyze existing electrochromic data, using this assumption, and report Δα values of 44 Γ…^3^ for coronene an
