Notes:
The low-frequency Raman spectra of tetrabromophthalic anhydride (TBPA) and its associated charge-transfer complex naphthalene-tetrabromophthalic anhydride (N:TBPA) have been recorded at 300 and 77 K. Nine lattice modes are identified for TBPA, the crystal structure of which is found to be unchanged in the range 300-77 K. On complexation, N:TBPA is observed to have a lowest frequency Raman band at 19 cm-1. Neither of its parent molecules have a Raman band with a lower frequency. The 19 cm-1 mode is assigned to the librational motion of the donor (naphthalene) and acceptor (TBPA) molecules of the complex along their stacking axis.
