The first paper introducing the low-frequency internal motions or phonons was proposed in 1977 . It has stimulated a series of follow-up papers in this very interesting field (see, e.g.,  - , as well as the eight master pieces of papers from the then Chairman of Nobel Prize Committee Sture Forsen   - .
It is indeed very significant by introducing the concept of low-frequency internal motions (phonons) for studying biomacromolecules and it is indeed very profound by doing the same.
