Optical Rotation in aqueous solution is reported for D and L crystals of Sodium Chlorate at different temperatures. After an initial high the rotation falls over time and then on moves in a zigzag fashion. The results show that the asymmetry in chlorate is real and is at the atomic level in contrast to the more common asymmetric carbon-derived molecular chirality. The observed zigzag pattern of changing optical rotation with time at a given temperature, is attributed to the intramolecular swing of the oxygen atoms from one chiral form to another without structural change; in other words chiral inter-conversion without structural change and not parity breaking.
