Abstract
Spin labels dissolved in highly purified fatty acid systems exhibit nearly identical tumbling rates in liquid and solid phases. Even though the spin labels do not have the same molecular geometry as the lipid matrix the melting point of the matrix can be inferred by measurements of the temperature dependency of molecular motion.
摘要
溶解在高度纯化脂肪酸体系中的自旋标记物在液相和固相中表现出几乎相同的翻滚速率。尽管自旋标记物与脂质基质的分子几何形状不同，但通过测量分子运动的温度依赖性，可以推断出基质的熔点。
