Abstract
The time differential perturbed angular distribution technique has bee n applied to studies in synthetic diamond grown by the chemical vapor deposition method. It was found that the F-19 nuclear probe used occup ies only one characteristic lattice site associated with a coupling fr equency of 63(3) MHz. This result represents a starkly different situa tion when compared with previous findings from extensive investigation s on three different types of natural diamond, as well as on synthetic diamond grown under high temperature, high pressure conditions. Such comparison has revealed the role of hydrogen in the different types of diamond and its particular chemical form of occurrence. As hydrogen s eems to play an important role in different methods of synthesis, thes e findings give a first insight into such synthesis aspects.
