## Abstract ^1^H, ^13^C and ^77^Se chemical shifts of sulphur and selenium analogues of furocoumarin are given. These data are very similar to the values obtained from benzofuran, coumarin and their sulphur and selenium analogues.

β¦ Synopsis
The fluorescence lifetimes of linear furocoumarin drugs and model compounds are reported in water, ethanol and water/ethanol mixtures. In most cases more than one lifetime is observed and this is discussed in terms of complex and excited-state complex formation between the solvent and furan moiety of the drugs.
