We constructed a computer controlled pulse programmer for the measurement of nuclear quadrupole resonance relaxation times. Programmable interval timer 8253 was used as device for pulse programming. The circuit is very simple and construction is also easy in comparison with the usual pulse programmer. This programmer is sufficiently useful concerning the pulse programming of slimple pulse sequences such as π-τ-π/2 and π/2-τ-π, which are usually used in the measurement of relaxation times. We tudied a Fourier Transform Spectrum and relaxation times using this pulse programmer.核四極共鳴緩和時間の測定のためのコンピューター制御のパルスプログラマーを作成した。これはプログラマブルインターバルータイマー8253を用いてパルスプログラミングを行っており,従来のパルスプログラマーと比較して,回路が非常に簡単で,制作も容易であるが,通常の緩和時間の測定で用いられるπ―τ―π/2 and π/2―τ―πの様な単純なパル...
