title: Etude par transformation de Fourier de CH(3)Br et CH(3)Cl dans l'infrarouge très lointain.
abstract: A high resolution Fourier transform spectrometer has been constructed for working in the far infrared region. After a description of this instrument, its performance in the 10-40 cm(-1) spectral region is demonstrated by studying the pure rotational spectra of CH(3)Cl and CH(3)Br. A working resolution of 0.05 cm(-1) is verified, and isotopic splitting is observed in CH(3)Br out to 14 cm(-1).
