WebIn this paper, a new method that can be used to modeling chiral metal complex by molecular mechanics in a PC has been explored. In this new method through the building and energy minimization of chiral metal complexes the optimal conformations are obtained, which is carried out on the base of MM2 force field from Cs Chem3D Package. WebA chemist received a report from an analysis involving the iron-phenanthroline method, containing the calibration curve for Fe standards (20 ppm, 30 ppm, 40 ppm, 50 ppm, and 60 ppm) and their corrected absorbances. The report stated that the equation of the line and r 2 were as follows: y = 0.015066 x – 0.154424 r 2 = 0.9997
