The vibrations of borazine derivative-I the planar vibrations of borazine and N-trideuteroborazine

The infra-red spectrum of H3Bi3N3H3 has been measured with 0.5 cm-1 resolution over the 4000-250 cm-1 region, and with lower resolution to 10,000 cm-1. Complementing the data with the known Raman active frequencies and those of the H3B3N3D3 infra-red spectrum, a normal co-ordinate treatment has been...
