Hlgh-resolutron emssion and excitation spectra are reported for a K2C1207 crwtal at 1.2 K, and rhc effect of mmowave saturation on these spectra is dacussed. In the 1-l 2 GHz regon resonances occur at 4.628 and 7.267 CHz, pro~ng that the em&on stems from a tripiet state no) The orzgms of the To-So a
