UV–visible spectroscopy written questions
Work through H3 Chemistry chromophores, conjugation, Beer–Lambert calculations and UV–visible analysis, with marking guidance for written answers.

- Relate electronic transitions and chromophores to UV/visible absorption
- Predict UV/visible absorption from a chromophore
- Explain conjugation, energy gaps and longer-wavelength absorption
- Use the Beer–Lambert law in concentration calculations
- Plan quantitative analysis using UV/visible spectroscopy
