The anticrossing spectra of the n = 6, 7, 8 /sup 1/D-/sup 3/D states of /sup 3/He has been observed. From these measurements precise values of the electrostatic singlet-triplet separation of these states have been obtained and are found to differ systematically from the accepted values of the /sup 4/He singlet-triplet separation by approximately 34 MHz. We have investigated mass dependent contributions to both the energy level structure and the magnetic-tuning characteristics of the states of interest. We have found no mechanism that can explain such a large difference in the electrostatic-energy separation of the singlet and triplet D states between the two helium isotopes.
