The ENDOR spectnun of the triphenylmethyl radical formed by heat treatment of triphenylmethane has been measured in solution at 131 "C. The derived hyperfine coupling constants of 2.770,2.556 and 1 . B G were used to simulate the extremely well resolved EPR spectnun. These coupling constants are in

β¦ Synopsis
The direct measurements of the principal thermal expansion coefficients were carried out for the specimens of pyrolytic graphite at temperatures between 50 and 55O"C, using an apparatus with high sensitivity. Resolving power of the apparatus was f 100 A. The c-axis thermal expansion coefficient was also directly measured for the specimens of kish graphite flakes.
