Spectroanalytical Methods

Spectroanalytical methods measure the wavelength and intensity of radiations that are either emitted or absorbed by a molecular or atomic species. These methods are useful for evaluating the electronic or atomic arrangement of the molecules of a given analyte.

Question

In the lab, you determined the wavelength whose absorbance was maximum. That wavelength
was used to measure the absorption ofeach of the standard solutions. With these data construct a
calibration curve.
Remember:
1. Properly identify the axes on the graph.
2. Use a suitable title that includes the wavelength of maximum absorption.
3. Include the equation of the straight line that best fits your values and the coefficient of
determination (R2, “R-squared").
