  • The temperature dependence of C-13 chemical shifts are observed for the cyclooctanone arylhydrazones. The temperature-dependent chemical shifts for these derivatives are explained by postualating the existence of two equilibrating structures. In addition, the assignment between the $^{13}C$ signals of methylene carbon pairs can be done by application of the ${gamma}$ -substituent effect.
