The high resolution infrared absorption spectra of $Cl3B3N3H3$ was run across the range $4000-230cm-1$ for gaseous, solid, and liquid solution samples; Raman spectra were obtained for the solutions. The previous contradictory assignments are discussed and a new one is proposed. Complementing the data with the known infrared active frequencies of $Cl3B3N3D3$, a normal coordinate treatment has been made. The force constants and potential energy distributions are compared with those obtained in our previous work on borazine, and a discussion is made of the chlorine substitution effect on the electronic structure of the ring.
