ESR experunents on the lummescent triplet state of trrclmic KzCT~O, are reported\_ For the A site D = 24.300. E = 2 324 GHz. for the B ste D = 26815. E = 3.683 GHz. From the pnnapakxis tirectlon of the ZFS tensor It follows that the excrtatron is loulized on one half of the G20~-ron. An analyns of

β¦ Synopsis
The zero-field spliltings and IifeGmrs of the phororxciIed IripIeI sxnzs in K2Cr207 and YVO, crys~nls hnvc been derermined by EPR enpcrimenls in zero field. The splilrings for K1Cr2_07 agree with the spin Hamilronian used previously for describing EPR cxpcrimenw in B magnetic lisld. Those for YVO, indrcnle a lowering of symms~ of the VO:-ion on encirarion.
