THIN-FILM FTIR TRANSMISSION SPECTRA OF LIQUID 2,4,6-TRIMETHYLPYRIDINE

Thin film transmission spectra of liquid sym-collidine were measured i n the region 4000-500 cm(-1) in cells with thicknesses in the range 3- 15 mu m. From these data, the spectrum of the complex refractive index was determined in this region. Forty absorption bands were detected a nd quantitatively described in terms of the band indices, half-widths and integrated intensities. The assignment of numerous bands is presen ted and discussed. The near-IR spectrum of the liquid is also reported . (C) 1997 Elsevier Science B.V.
