概要
- 論文の詳細を見る
Ultrasonic velocity and absorption in liquid diiodomethane have been measured in the frequency range 100 MHz〜1. 7 GHz at the temperatures of 10゜ and 20゜C using the highresolution Bragg reflection method. Vibration relaxation was observed which was ascribed to all the vibrational modes except the lowest. Vibrational relaxation frequency β in fifteen liquids obtained in our previous and works is plotted as a function of fundamental vibration frequency ν of the relavant trigger mode. The relation log β=A-κν well fits the data within the fact of two, where A and κ are constants. This indicates fundamental vibration is a dominant factor in determining relaxation frequency.
