In this article we show that there are invariant distances on the monoid L (A) of all strings closely related to Levenshtein's distance. We will use a distinct definition of the distance on L (A), based on the Markov -Graev method, proposed by him for free groups. WebThe number of vibrational normal modes can be determined for any molecule from the formula given above. For a diatomic molecule, N = 2 so the number of modes is 3 × 2 − 5 = 1. For a triatomic linear molecule (CO 2 ), it is 3 × 3 − 5 = 4 and triatomic nonlinear molecule (H 2 O), it is 3 × 3 − 6 = 3 and so on.
