Abstract
The electric dipole moments in the ground mu (g) and excited mu (e), state of the fluorescent probe LAURDAN are determined from solvatochromic and the rmochromic shifts to be mu (g) = 3.46 D, mu (e) = 10.6 D and mu (g) = 3.76 D, mu (c) = 10.24 D, respectively. These values concern the free LAURDAN mo lecule. The values of the dipole moments of LAURDAN (= 6-decanoyl-2-dimethy lamine-naphthalene) exceed distinctly those of PRODAN (= 6-propionyl-2-dime thylamine-naphthalene).
