“…44 Instead we reassign a spectrum with a band origin of n 0 = 74 271 cm À1 , which has been assigned to the f 3 D 2 [3/2]7pp(v 0 = 0) state before, 44 to the F 1 D 2 [1/2]6pp (v 0 = 2) state with d = 3.59 in perfect agreement with the same value (d = 3.59) for both F 1 D 2 [1/2]6pp (v 0 = 0) and (v 0 = 1) states. 28,30,44 A gradual decrease in the B 0 values with v 0 for the vibrational states of F 1 D 2 [1/2] 6pp from 6.32 cm À1 (v 0 = 0) 28,44 to 6.13 cm À1 (v 0 = 1) 30,44 to 5.93 cm À1 (v 0 = 2), 44 as expected, further supports this reassignment.…”
