PPT-Colors and Spectroscopy of Transition Metal Complexes

Why is Mn 2 aq colorless Cu 2 aq less deeply blue colored than CuNH 3 4 2 Zn 2 aq colorless MnO 4 deeply colored WCO 6 colorless Sigma Interaction Strength. Shera Casseus. Purpose of Lab. The purpose of the Pigment/Paint lab is to create pigments for painting using transition metal compounds.. . Vocabulary . Pigments. - Used for coloring paints, ink, clothing and food. Pigments gets their color from transition metals.. The interactions of the d orbitals with their surrounding chemical environment (ligands) influences their energy levels, and this coupled with the variable number of electrons (and incomplete filling of the d block) imparts on transition metals a unique, rich, and diverse chemistry.

Time dynamics. 2. UV Spectroscopy. Introduction. UV radiation and Electronic Excitations. The difference in energy between molecular bonding, non-bonding and anti-bonding orbitals ranges from 125-650 kJ/mole. This energy corresponds to EM radiation in the ultraviolet (UV) region, 100-350 nm, and visible (VIS) regions 350-700 nm of the spectrum. . . IMMUNS.  : HS III. I/ INTRODUCTION .
