## Abstract The molar Kerr constants and the dipole moments of __r__‐2‐__cis__‐5‐dimethyl‐__trans__‐5‐ø‐1,3‐dioxane (1), __r__;‐2‐__trans__‐5‐dimethyl‐__cis__‐5‐ø‐1,3‐dioxane (2), 2‐methyl‐5,5‐di‐ø‐1,3‐dioxane (3), __cis__‐2‐methyl‐4‐ø‐1,3‐dioxane (4)‐2‐__cis__‐6‐dimethyl‐__cis__‐4‐ø‐1,3‐dioxane (5
Whereas simple 4,4Ј-bi(1,3-dioxanyl)s 16 and 19 displayed little conformational preference at the inter-ring bond, their derivatives 4 and 13, with equatorial methyl groups in the 5and 5Ј-positions, each showed a strong conformational preference to populate a conformation with a gauche arrangement o
