Absorption Spectroscopy

A method which measures the ability of particles—solutes—in a solution to absorb light over a range of wavelengths.
Mechanism Because each compound absorbs light differently, absorption spectra are compound-specific and can be used to measure solute and solvent concentrations and determine reaction rates.

Al-Biruni and Ibn Sina did not have the advantage of using X-ray absorption spectroscopy to investigate the structure of water, but both of them were scientists whose worldview was informed by the Qur'an and both of them knew that there were signs in the water pouring down from the sky, giving life to earth after it had become lifeless, causing all manner of living creatures to multiply thereon (al-Baqarah:164).
