N2  - Signal intensities of the 35Cl nuclear quadrupole transition in para-dichlorobenzene, obtained using a frequency modulated superregenerative spectrometer, are investigated as a function of quenching frequency. The quenching voltage is applied in the form of pulses of variable on (ton) and off (toff) times. A method is provided for the calculation of (Vs2/Vn2)½ which appears in the detection equation     &#916;A = aV0In(1 + Vs2/Vn2)½  By applying the theory of nuclear induction to a series of pulses, such as those of a super-regenerative oscillator, it is possible to explain the observed behaviour of signal intensities with operational characteristics and solid state relaxation parameters.
