Homework Help: Rigidity of a spring

  1. Aug 31, 2010 #1
    I have a question regarding calculationg the effective spring constant, K, for a CO molecule. The actual question regards the relation between the angular frequency for the molecule and the rigidity K. Look at my teachers solution he gives the following formula relating those:

    K(CO) = m'*w^2

    , where m' is the reduced mass for the CO molecule and w is the angular frequency. I dont understand this formula at all, where does it come from? If someone has some insights in this, please help :)

    When you say something about spring, spring constant, etc, when it comes to things other than a real spring, it has to be a model. So how did you model CO molecule? Analyze the model and you will see the answer :wink:
