Advanced Studies,Okazaki 444-8585 Japan Department of Applied Physics,University of Tokyo,Hongo, Bunkyo-ku, Tokyo 113-8656 Japan X-band ESR measurements of BIP-TENO (3,3′5,5′ -tetrakis(N-tert-butylaminoxyl)biphenyl) single crystal, which is an S = 1 spin ladder model substance, have been performed in the temperature region from 3.5 to 300K. At room temperature, the angular dependences of g-value and line width were observed. The line shape and the angular dependence of the line width showed typical behavior of a low-dimensional antiferromagnet. The temperature dependence measurements showed the minimum of the line width and the dynamical g-shift, which were also typical behaviors of a low-dimensional antiferromagnet. However, the direction of the dynamical g-shift does not coincide with Nagata's well-known theory, and the comparison with the recent direct ESR calculation by Miyashita et al. [S. Miyashita, T. Yoshino and A. Ogasahara: J. Phys. Soc. Jpn. 68 (1999) 655] is discussed.
