Question
1.If the left hand side of the plot is the lower wavelength of the UV-Vis scale, approximate the lambda max for the compound that produced the spectra below. (assume wv on the x-axis are presented in a linear manner and make approximation). Use approximation to predict most likely color of the solution?
2.The lambda max is used because the absorbance data collected at that point minimizes error. The error source comes from the fact that when the light is separated to produce a single wavelength the grating doesn
Explanation / Answer
1)towards right wavelength is increasing so in visible range, the color of the solution will be violet or blue color.
3) small peak is due to d-d or n-> pi* transition which is of low intensity.
2)It is because, at the peak absorbance, the absorbance strength of light will be maximum and the rate of change os absorbance with wathlength will be lowest.
