Data associated with a tellurium absorption atlas 19,000 - 24,000 cm^-1

Area of Science:

• Atomic and Molecular Spectroscopy
• Physical Chemistry
• Materials Science

Background:

• Accurate spectral calibration is crucial for analyzing molecular and atomic species.
• Tellurium (Te) vapor spectra are complex and require detailed atlases for precise identification.
• Fourier transform spectroscopy (FTS) is a powerful technique for obtaining high-resolution spectra.

Purpose of the Study:

• To generate a comprehensive spectral atlas of 130Te vapor.
• To provide reference data for spectral calibration in the blue-green to violet wavelength range.
• To support research in molecular spectroscopy and related fields.

Main Methods:

• High-resolution Fourier transform spectra were recorded using a commercial Bomem DA3 instrument.
• A sealed, evacuated cell containing 130Te was heated in a ceramic furnace to approximately 620 °C.
• Tellurium vapor pressures were maintained between 8-11 Torr during spectral acquisition.

Main Results:

• Transmittance and absorbance data were collected, forming a detailed spectral atlas.
• The spectral atlas covers the blue-green to violet region.
• The obtained spectral data are directly applicable to spectral calibration.

Conclusions:

• The generated spectral atlas of 130Te vapor serves as a valuable tool for spectroscopic calibration.
• This work facilitates more accurate analysis of spectra in the specified wavelength range.
• The data contribute to the broader understanding of tellurium's spectral properties.
