• Single crystal [(III) and (100) planes', and powder ESR of Mn" (substitutingfor Ca") in Ca.Ba(C.H5C00),; in the temperctture range 220'C to -]60'Cshows (i) a doubling of both the physically and chemically inequivalent sites, anda change in the magnitude (150 G at - 6'C to 170 G at - 8'C) as well as theorientation of the D tensor across the -6'C tx"ansition and (ii) an inflectionpoint in the D vs T plot across the - 75'C transition. The oxygen octahedraaround the Ca" sites are inferred to undergo alternate rotations, showing theparticipation of the carboxyl oxygens in the -6'C transition. A relation of thetype D=D.(1-l-ctT-lflT") seems to fit the D variation satisfactorily.
