我们在前面[1,2]中表明,在顺磁离子存在下磷脂膜的PMR光谱使得有可能区分来自膜的内表面和外表面的信号,因为来自外表面卵磷脂分子的N+(CH2)质子的信号与来自内表面质子的信号相比有相当大的位移。
We showed earlier [1, 2] that PMR spectroscopy of phospholipid membranes in the presence of paramagnetic ions makes it possible to distinguish between signals coming from the inner and outer surfaces of a membrane, since the signal from the N+(CH,), protons of the outer surface lecithin molecules is considerably shifted in comparison with the signal from the inner surface protons.
