We have studied a thallium-deficient (Formula presented)(Formula presented) (TDP) sample in the temperature range 130-400 K using 200 MHz (Formula presented) pulsed NMR. The line shape consists of a broad and a sharp line, corresponding to the TDP phase and a thallium-deficient phase, respectively. The rotating frame spin-lattice relaxation was shown to consist of two separate components each corresponding to the two line shape components, and to sensitively reflect the phase transitions and the proton motions.
