N2 - We study the (Formula presented) quantum spin chains with bilinear, biquadratic, plus bond alternation in the vicinity of the (Formula presented) Takhtajan-Babujian model. Transition line between the Haldane and the dimer phases is determined numerically. To see the crossover behavior from (Formula presented) SU(2) Weiss-Zumino-Witten (WZW) model] at the Takhtajan-Babujian point to (Formula presented) SU(2) WZW model], we calculate the conformal anomaly c and scaling dimensions of the primary fields on the transition line.
