Normal Modes Of Vibration Ch 431 Inorganic Chemistry

Normal Modes Of Vibration Ch 431 Inorganic Chemistry

So the three normal modes of vibration for water have the symmetries A 1, A 1 and B 1. We now have a general method for determining all of the fundamental modes of vibration for a molecule and expressing these modes in the shorthand language of Mulliken symbols. This is one of the exercises that you will be tested on in Exam 1.
