We study the contribution of various vibrational modes to the melting of poly(dG).poly(dC). We find that the principal contribution comes from the H-bond breathing modes that have been observed in Raman scattering and that we have associated with helix melting. We show the softening of these modes on approach to melting in agreement with the observed behavior. We also describe the contribution to melting from base rotation modes that others have suggested are important in melting.
我们研究了各种振动模式对聚（dG）·聚（dC）熔化的贡献。我们发现主要贡献来自于在拉曼散射中观察到的、且我们已将其与螺旋熔化相关联的氢键呼吸模式。我们展示了在接近熔化时这些模式的软化，这与观察到的行为一致。我们还描述了其他人认为在熔化过程中很重要的碱基旋转模式对熔化的贡献。
