In this paper we studied Photo physical properties and estimated ground and excited state dipole moments of Acridine Orange Hemi Zinc salt and Acridine Yellow G laser dyes with help of various solvatochromic methods which considers bulk solvent polarity parameters and compared with theoretically estimated values which considers microscopic polarity parameters. We calculated the angle between ground and excited state dipole moments for both molecules. This paper reports that both molecules are PH sensitive due to presence of central protonated nitrogen atom, That PH sensitivity leads to efficiency loss as compared with other dye like acriflavine.
