Complex Molecular Biotechnology, Organic Analytical Chemistry,. Organic  His early work on stereochemistry explained optical activity in terms of the tetrahedral bonding of carbon atoms in organic molecules. His later work outlined the  Metabolic and chemical criteria might be used for detecting life with in situ studies. Direct tests of soil or water for optical activity might be made.

OES: optical emission spectroscopy, a multielement detection method used primarily for metals.

Optical activity is measured by a polarimeter, and is dependent on several factors: concentration of the sample, temperature, length of the sample tube or cell, and wavelength of the light passing through the sample. Rotation is given in +/- degrees, depending on whether the sample has d- (positive) or l- (negative) enantiomers. Chiral organic compounds isolated from living organisms are usually optically active, indicating that one of the enantiomers predominates (often it is the only isomer present). This is a result of the action of chiral catalysts we call enzymes, and reflects the inherently chiral nature of life itself. The ability of a solution to rotate plane-polarized light in this fashion is called optical activity, and solutions which have this ability are said to be optically active.

It is measured by an instrument polarimeter. Optically active compound tends to show rotation  What is it? Optical isomerism occurs when substances have the same molecular formula and structural formula, but one cannot be superimposed on the other. Different chiral molecules will have optical rotations that vary in direction and size of the optical rotation.
