Find the group symmetry for time translation and rotation . What are the generators associated with these?
NO3- nitrate ion, what is the symmetry operationof rotation of it?
Question 0.3. What is the size of the symmetry group of a regular tetrahedron? By "symmetry" here, let's mean "rigid (distance- and orientation-preserving) linear transformations of R3" --so, no flips, to make it easier. You may consider flips too if you like. Once you know the size, can you list all the distinct symmetries?

For the ammonia molecule NH3, use the group theory to find the number and symmetry species of the Raman and infrared active vibrations. Note: when finding the characters for C3 rotation, you will need to use the concept of the rotation matrix to treat the atoms that do not change positions.
