A study of dielectric relaxation time with pressure for vitamin D-3 in powder form

In this work, a sample of vitamin D/sub 3/ in wafer form prepared by special technique and subjected to different pressures in the range of 5 to 8 tons, subjected to high frequency perturbations in the range 10 to 30 MHz yield the relaxation times in the range of 7.58 n sec to 14.47 n sec. The results are explained on the basis of existing theories and the recent results of Li Shengtao et al. (1991) and Manabu Takeuchi (1991).
