title: Comment on "Improvement of the Davydov theory of bioenergy transport in protein molecular systems".
abstract: It is shown that a certain wave function represents a two quanta state of the Davydov-Scott model, contrary to the claims of Pang. Furthermore, Pang's choice of wave function and derivation of equation of motions are criticized. Directions for future work in this area are indicated.
