Abstract
We have performed ESR measurements on the S = 1/2 double-spin-chain sy stems KCuCl3 and TlCuCl3 using single crystals. The ground states of t hese compounds are spin singlet and there are finite gaps in their exc itation spectra. The temperature dependence of the paramagnetic resona nce intensity is similar to that of susceptibility. The direct transit ion from the singlet ground state to the excited triplet state is obse rved for both compounds. (C) 1998 Elsevier Science B.V. All rights res erved.
