摘要：

A sample containing 20 wt % of the nonionic surfactant tetraethylene glycol dodecyl ether (C12E4), specifically deuterated in the alpha-position, was investigated with H-2 NMR relaxation in H2O. From the frequency dependence of the longitudinal relaxation rate in the Larmor frequency range 2-55 MHz, it was concluded that the solution contains rodlike micelles. A slow motion in the microsecond time scale, as determined from the transverse relaxation rate, was interpreted taking the flexibility of the rodlike micelles explicitly into account.
