The spectra of the real and imaginary components of the complex electr
ic permittivity of liquid tri-n-octylamine were determined in the visi
ble, near infra-red and mid infra-red regions (25 000-600 cm(-1)). Rel
ated high-frequency dielectric properties of the liquid were determine
d and are discussed. (C) 1997 Elsevier Science B.V.
