| Abstract: | This paper describes the design and construction of a personal computer (PC) based pulsed NMR spectrometer to measure spin-lattice relaxation times in solids. The spectrometer works at 10 MHz and produces r.f. pulses of amplitude 200 Vp-p. The pulse programmer provides various pulse sequences such as 180°-τ-90°and 90°-τ-180°and inter pulse intervals (τ) can be computer programmed. The rise and fall times of r.f. Pulses are less than 0.4 µs. The rejection ratio of the transmitter is better than 3 x 107. The overall gain of the receiver system is 120 dB with a band width of 2 MHz. The recovery time of the receiver is 7 µs. The PC controls the spectrometer and data acquisition system. A detailed description of the spectrometer is presented. |
