Abstract
Alkali 〈I⋅S〉 wall relation rates for Pyrex resonance cells coated with dichlorodimethylsilane have been studied. In particular, by considering the ratio of the Rb85 wall relaxation rate to the Rb87 wall relaxation rate, evidence is presented showing that dimethylsiloxane surfaces and alkane (paraffin) surfaces relax alkali polarization with similar interaction strengths and correlation times. This conclusion indicates that the outer most functional group of an organic surface molecule has the primary influence on the alkali polarization’s surface relaxation.
