Measurements of the variation of ultrasonic second harmonic wave amplitudes with the specimen temperatures and the fundamental wave amplitudes are made in molecular crystal naphthalene by using a modified pulse echo technique. Explanation of the experimental results is given and problems for further investigation are suggested.
