Abstract
Optical activity generated by the rotational normal coordinates is investigated. The theoretical formulation is based on classical principles and uses the definition of the rotational normal coordinates and the changes in electric and magnetic dipole moment componenets along that rotational circular dichroism (CD) is supported by chiral asymmetric top molecules whereas rotational Raman optical activity (ROA) is supported by the chiral asymmetric top and as well as symmetric top molecules. For a two group molecule of $C_{2}$ symmetry, rotations around the two principal axes perpendecular to $C_{2}$ axis are noted to generate opposite signed CD. Also opposite signed ROA is predicted for these rotations in a two group molecule.
