Abstract

Transmittance and absorbance data in the form of a spectral atlas have been obtained from Fourier transform spectra recorded on a commercial (Bomem DA3) instrument, operated with an external white light source injected through the instrument's `emission' port. The sample was a sealed, evacuated cell containing a small quantity of 130Te. This cell was placed in a ceramic furnace maintained close to 620 °C, with tellurium vapor pressures 8-11 Torr. The data are intended as an aid to spectral calibration in the blue-green to violet region. The data relate to work published in J. Mol. Spectrosc. 384 111,589 (2022).

Keywords: Fourier transform spectrum of tellurium dimer; Te2 absorption; Te2 reference spectrum; Tellurium atlas.

Diagram of the optical arrangement used to record the spectra. L1, L2 and L3 are convex lenses with focal lengths 4, 6 and 4 cm respectively, chosen to match the f/4 aperture of the FT interferometer and the physical diameter of the tellurium cell. The external filter is drawn tilted; we used combinations of interferential high- and low-pass filters from Corion Inc; their optical response can be (and was) tuned by changing the angle of incidence.
