Abstract
We present results from magnetic-resonance measurements for 75-350 GHz in alpha'-NaV2O5. The temperature dependence of the integrated intens ity indicates that we observe transitions in the excited state. A quan titative description gives resonances in the triplet state at high-sym metry points of the excitation spectrum of this spin-Peierls compound. This energy has the same temperature dependence as the spin-Peierls g ap. Similarities and differences with another inorganic compound CuGeO 3 are discussed.
