The complex [Fe(H2O)6]3+ has a maximum absorbance at 724 nm. a.Calculate the crystal field splitting energy, in kJ, for the complex. b.Predict the colour of the complex.
An octahedral metal complex absorbs light with wavelength 580 nm. a. What is the crystal field splitting A, in kJ/mol for the complex? (Hint: Energy is based on wavelength of light absorbed. See data sheet.) (3 marks) b. What color does the complex appear to the eye? (2 marks) 750 nm, 400 nm Red Violet 630 nm 430 nm Blue Orange 590 nm 480 nm Yellow Green 560 nm
620 nm Estimate the wavelength of maximum absorption for the octahedral ion trioxalatochromate(III) from the fact that light transmitted by a solution of it is violet. Hint: use the color wheel to the right. 800 nm 400 nm → red orange 580 nm violet yellow Estimate the crystal field splitting energy A. (in kJ mol-?). blue green kJ mol-1 560 nm 430 nm 490 nm
A ?1 octahedral complex is found to absorb visible light, with the absorption maximum occurring at 499 nmCalculate the crystal-field splitting energy, Δin kJ/mol.
Emission line spectra for various elements are shown in Table 1 and Table 2 shows the wavelengths for various colors. Remember, E = h*c/?, where E is energy, h = 6.626*10-34 J*s, c = 3.00*108 m/s, ? is the wavelength, and 1 m = 109 nm. Table 1.

Based on table 1, why Lmax shifts towards higher wavelengths when you go from ethylene to b-carotene? Figure 1. violet blue green yellow orange red purple 500 800 nm The greater the degree of conjugation of chromophores the greater the chance that the absorption of light will occur at higher wavelengths. Table 1 illustrates the effect of conjugation (where max gives the wavelength of maximum absorption): # of conjugated double bonds 175 Table 1.

1) Write a Reaction equation using 4- aminobenzenesulfulfonic acid (aniline derivative) and 8-anilino-1-naphthalenesulfonic acid (coupling agent). Write the mechanism. SYNTHESIS OF AZO DYES INTRODUCTION Humans' love of color dates back almost to prehistoric times, yet it is not actually until the modern era that the full range of the rainbow has been accessible to the majority of people irn their clothes and other textiles. Ancient or medieval times have often been described as being quite splendid with their "tyrian purple"...
