Simulated Spectra and Comparison with Experiment

COMPUTER-SIMULATED SPECTRA AND COMPARISON WITH EXPERIMENT 

Do and Eo can be determined in glasses when Do is small. On the other hand, when Do is large (Do/g/ 10,000 G), flien variable temperature measurements will allow determination of die signs for D, E. Zero-field EPR may also be used to determine the signs of D, E. 

Effect of Distribution of Fine-Structure Parameters D and E on the Shape of EPR Spectra 

When AD = A = 0, it is seen from (51) that the lines and peaks in the powder EPR speetra oecur at resonanee-field values for whieh grad = 0, i.e., 

It can be shown that for each hypcrfinc transition six different types of critieal points oeeur at definite values of 0o, q o which are as follows
