Abstract

The electric dipole moments in the ground /µg and excited state of the fluorescent probe LAUR-DAN are determined from solvatochromic and thermochromic shifts to be /µg = 3.46 D, µe = 10.6 D and /µg = 3.76 D, /µe = 10.24 D, respectively. These values concern the free LAURDAN molecule. The val-ues of the dipole moments of LAURDAN (= 6-decanoyl-2-dimethylamine-naphthalene) exceed dis-tinctly those of PRODAN (= 6-propionyl-2-dimethylamine-naphthalene).

Keywords: Solvatochromic and Thermochromic Shifts; Dipole Moments in the Ground and Excited States; LAURDAN-Fluorescent Probe
