The seven elastic compliances and seven elastic constants of single crystal calcium molybdate were determined by a resonance method. The compliance s 16 , which is zero for higher symmetry tetragonal crystals, need not be zero for crystals of lower tetragonal symmetry and contributes significantly to the orientation dependence of the elastic moduli of calcium molybdate. The values of the compliances and their standard errors (based on 41 measurements) in units of 10 −11 m 2 /N are s 11 = 0.974 + 0.005, s 33 = 0.958 ± 0.004, s 44 = 2.720 ± 0.009, s 66 = 2.471 ± 0.022, s 12 =−0.380 ± 0.010, s 13 =−0.230 ± 0.009, and s 16 = 0.433 ± 0.010.
