“…Therefore, we approximate the problem as the interaction of the rotation-averaged oscillator with the nonvibrating rotator. The 0a averaged potential can then be obtained as (5) U(r2). These integrals as well as , and ' cannot be integrated in analytical forms; we shall carry out integration numerically for given values of a.…”

Hyung Kyu Shin the 5Gj states can be assigned. We show the detail of the band at 26,000 cm™1 (388 µ) in Figure 10 with two transition$ indicated. There are 11 Stark components whose widths vary between 5 and 8 Á in contrast to those of Figure 7 for Pr3+ xvhere the half-widths were closer to 25 Á.Up to this point we have accepted the concept of identifying corresponding terms of a given multiplet if one or more was unquestionably present. Now we can take the opposite viewpoint and search to determine if all terms of a given multiplet can be found.To do this, we examine the data of Figure 11 for Tb3+ in TbP04. The lowest state is unquestionably 5D4. The other 5Dj states are apparent as are the 6Gj states. By close inspection of Figure 11 we can also assign 5H and 5I transi-tions. The band at 38,000 cm™1 is very broad (about 90 Á in half-width). We have reason to assign it as a 5Fj state and this will be the subject of a further communication.12 Another case where all of the terms of a multiplet are present in the spectrum is evident in Figure 12 for Eu3+ in EuP04. The 7Fi state is thermally accessible at room temperature and is populated. Thus there appears in the spectrum what might at first glance seems to be doublets. These are lines for the 5D states, one from the 7Fq and the other from the 4 term of the ground state. All of the terms can be correlated to line doublets in the spectrum. Not all of the 5H terms appear to be present. This may be due to the fact that the 4f states above about 34,000 cm™1 are obscured by the charge transfer band of Eu3+.
