What is the Beer-Lambert law formula?
Think about what the variables represent.
Define molar absorptivity.
It is important to know its unit of measurement.
What does the Beer-Lambert law relate to?
Focus on what each term of the law signifies.
True or False: Molar absorptivity is higher in IR spectroscopy than UV-Vis.
Consider the differences in optical properties of these spectroscopies.
Given the absorbance of a solution as 0.75, and knowing the molar absorptivity is 500 L mol⁻¹ cm⁻¹, calculate the concentration when the path length is 2 cm.
Rearranging the Beer-Lambert law will be essential.
If two compounds have overlapping IR peaks, how can you identify them separately? What strategies can you suggest?
Think about mathematical techniques that could aid in separating signals.
