Study of Chlorophyll a by Linear dichroism (LD) (CAT#: STEM-ST-0122-WXH)

Introduction

Chlorophyll allows plants (including algae) to photosynthesize, i.e., use sunlight to convert simple molecules into organic compounds. Chlorophyll a is the predominant type of chlorophyll found in green plants and algae.

Principle

Linear dichroism (LD) or diattenuation is the difference between absorption of light polarized parallel and polarized perpendicular to an orientation axis. It is the property of a material whose transmittance depends on the orientation of linearly polarized light incident upon it. LD measurements are based on the interaction between matter and light and thus are a form of electromagnetic spectroscopy.

Applications

Study the functionality and structure of molecules.

Materials

• Polarizer
• Absorbance spectrometer
