Abstract

In this research, some important physical properties of Rhodamine 6G dye, a type of Xanthine dye, whose emission is located between (0.5-0.7)µm. were studied double bond [C=C],[C=H] and [C=N] ,addition singular for the bonds [C-C],[C-N],[C-H] and [C-O] ,the calculation of the constants of forces. Here, too, the double bond was the largest value than the singular,the same thing applies when the value of the heat of formation for each bond was calculated and two programs were used, the first for drawing and the second for the calculations, which are (CS Chem Draw 5.0 Manual,CS Chem Office Pro 2000) respectively, and when calculating the vibrational patterns of the bonds, the double bond was the least patterned. Calculation of the streatching vibration patterns, bendening vibration patterns, and streatching - bendening patterns of the dye, and finally the calculation of the HOMO –LUMO forms and the drawing of their shapes.
