The elastic constants 'of no crystal belonging to the crystal class 4, 4^^-, 4/m have yet been determined. Pentaerythritol belongs to the 4^^-crystal class. All seven elastic constants of it have been determined by the study of (200), (202) and (004) diffuse reflections with [010] axis and, (200) and (220) diffuse reflections with [001] axis perpendicular to the direction of incidence of the X-rays. The value of the elastic constants thus determined is given below in units of 10^<10> dynes/cm^2. C_<11> = 6.1, C_<33> = 8.0, C_<44> = 3.5; C_<66> = 4.6, C1_<16> = -0.39, C_<13> = 0.50, C_<12> = -2.5
