Can I read Absorption Spectra of Leaf Pigments on EtoBox?

Absorption Spectra of Leaf Pigments by Allaine Garcia is a document available to read on EtoBox.

What is Absorption Spectra of Leaf Pigments about?

The document describes an experiment to determine the absorption spectra of four photosynthetic pigments - carotene, chlorophyll a, chlorophyll b, and xanthophyll - found in leaves. Paper chromatography is used to separate the pigments from a leaf extract. The extracts are then placed in a spectrophotometer to measure absorbance at wavelengths from 400-700nm at 50nm intervals. The class data is averaged and graphed to compare the absorption spectra of the different pigments.
