**Circular Dichroism**

- How can one obtain Molar differential extinction coefficient?

From the CD spectrometer you can obtain degrees or milli degrees.

**molar differential extinction coefficient = milli degrees / (32980 ×**

*c***×**

*l*)where

*c*is the molar concentration of the sample and

*l*is path length in cm.

- How can one obtain the
*g*-factor?

*g*-factor =**molar differential extinction coefficient /**

**extinction coefficient =**

**milli degrees / (32980 ×**

*A*)where

*A*is the absorption.
