In contrast, linear molecules have 3 translational and only 2 rotational, and to keep a total of 3N degrees of freedom, they have 3N-5 vibrational degrees. Tin, Sn, has many non-bonding electrons which also cause repulsions making the molecule angular so that all these electrons are as far apart as possible. Erik Kelderman Molecules for second order non-linear optics. By using our services, you agree to our use of cookies. It follows that the orientation of the nuclei of the (rigid) molecule is completely specified with only two Euler angles, φ and θ, not three as was the case for non-linear molecules. Overview and Key Difference This book presents an excellent overview of the exciting new advances in nonlinear optical (NLO) materials and their applications in emerging photonics technologies. The bond angles of these molecules differ from each other according to the shape. Here is my analysis for a diatomic molecule, if there are two atoms, we have to use 3 coordinates to describe the translational motion, 2 coordinates about the rotation and 1 for vibration, so total will be 6 degree of freedom for diatomic molecule.
