The point groups,ny new kind of matrix that can be generated from these by multiplication must also be accepted as a symmetry matrix on its own. In this chapter we will do exactly that, producing three new kinds of symmetry matrices that apply to molecules. That will make five kinds in all.

Recognizing matrices,y are especially simple, they look just about like any other 3-by-3 real numerical matrix filled with values between . and .. In this chapter we develop numerical tests to distinguish them, and to extract the axis and the angle. These tests are collected together in a useful operator named ., based

Introduction to the character table,ter table at this point we give can perhaps rouse a little curiosity about these theorems. We provide forward links to them as we go; if you are reading this chapter as review the links should prove especially useful. We cannot describe the character table without the new term . and an adjective for
