氘代磷脂双层的2H NMR横向弛豫速率反映了双层膜中的慢运动。在烃链的几个位置上特别氘代的二肉豆蔻酰卵磷脂的研究表明，这些运动是合作的，并仅限于脂双层的烃链。然而，脂质头基的相互作用确实发挥了重要的作用，在调制的烃链的合作波动（董事波动）的属性，证明了各种脂质添加剂对2H NMR横向弛豫速率的二肉豆蔻酰卵磷脂双层的影响。
The 2H NMR transverse relaxation rates of a deuterated phospholipid bilayer reflect slow motions in the bilayer membrane. A study of dimyristoyl lecithin specifically deuterated at several positions of the hydrocarbon chains indicates that these motions are cooperative and are confined to the hydrocarbon chains of the lipid bilayer. However, lipid head group interactions do play an important role in modulating the properties of the cooperative fluctuations of the hydrocarbon chains (director fluctuations), as evidenced by the effects of various lipid additives on the 2H NMR transverse relaxation rates of the dimyristoyl lecithin bilayer.
