The ground-stale recovery. ercikd-smle absorprion and sumula~ed emissmn gain temporal profiles or crystal violet have been mc;Lsured in a series of normal alcohol solutions The fluores=nce lime has been round 10 be Taster than Ihe excited-slalc lilclime in all the solvenfi sudred. A hear viscosrty dependence has been obsenvd [or Ihe ewlled-smle ab.orption and ground-slate recover) limes in the lowest-viscosity solutions. A simple model which is consislcnt with current theories for bamerless Isomerization is proposed

## Abstract **The cover picture shows**…︁‥the solvent effect of water upon the lowest‐lying singlet excitation in acetone. The transition, which involves the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO), is blue‐shifted in water (sol) with respect to
