Frequently asked questions
- What is molar absorptivity?
- Also called the molar extinction coefficient (ε), it is a measure of how strongly a substance absorbs light at a given wavelength. Units: L/(mol·cm).
- When does Beer-Lambert law break down?
- At high concentrations (above ~0.01 mol/L) due to molecular interactions, or when the light source is not monochromatic.
