## Abstract ^13^C NMR spin‐lattice relaxation times (__T__~1~) have been measured as a function of temperature for three 2‐phenyl‐1,3,2‐dioxarsolanes. The __T__~1~ data have been interpreted in terms of isotropic overall molecular reorientation, internal rotation about the AsPh bond and internal m
