Abstract
The Raman data for TlNO3 (mp 206°C) in the pure molten state are: 1036 (10, p), 1328 (3.3, dp), 1383 (3.9, dp), and 1637 (2.5) cm—1, and two relatively low frequencies, 708 (1.3) and 813 (1.7) cm—1. The results are examined in light of the vibrational assignments for D3h and C2v point group symmetries in solid-state nitrates, and for D3h symmetry for related nitrates in the molten state. An assignment of the Raman activity of molten TlNO3 based on retention of D3h symmetry is advanced; the appearance of the Raman ``forbidden'' frequencies (v2) and the loss of degeneracy (v3) are attributed to cationic environmental effects in this molten salt.
