INVESTIGATION IN SPECTROSCOPIC CHARACTERISTICS OFRHODAMINE C IN 1- BUTANOL

This research investigation is interesting to obtain information of absorption and fluorescence spectrum of the Rhodamine C dye in 1- butanol and the variations which happened in diverse concentration (1*10-5, 2*10-5, 4*10-5, 6*10-5, 8*10-5and 1*10-4) mole/l at ambient temperature.The outcomes obtained showed thatthere was a red shift with increasing concentration,theenergy gaps decreasingfrom (2.168 to 2.1 eV)with increasing concentration. Also the extinction coefficient, real and imaginarydielectric constants are in agreement with resulteddata.
