Abstract
Interaction between morpholine and a synthetic ligand (2,4,6-trimorpholino-1,3,5-triazin) with iodine was investigated spectrophotometrically in chloroform and dichloromethane solutions using soft-modeling approaches. Multivariate curve resolution-alternating least squares (MCR-ALS) and rank annihilation factor analysis (RAFA) methods were used for complete resolution of the measured spectrophotometric data. The concentration and spectral profiles of all species were calculated without any assumption of the chemical models and the complex formation constants in different solvents were determined. The influences of solvent properties on the formation constant of the resultant charge transfer complexes were discussed.
