TY - JOUR T1 - Isotropic and anisotropic environment effect on absorption spectra of Coumarin 504 TT - بررسی ‌ اثر محیط های حلالی همسانگرد و ناهمسانگرد بر طیف جذبی رنگینه کومارین 504 JF - opsi JO - opsi VL - 20 IS - 0 UR - http://opsi.ir/article-1-70-en.html Y1 - 2014 SP - 73 EP - 76 KW - absorption spectra KW - liquid crystal KW - polarity solvent parameter KW - solvent-solute interaction N2 - Absorption spectra of Coumarin 504 have been recorded in isotropic and anisotropic solvents. The maximum absorption wavelength of a dissolved dye depends on the solute –solvent interactions and solvent nature and can be used to describe interactions between solvent and solute molecules.
