Spectroscopy and electronic structure of the low-energy states of ThN

Te2 absorption spectrum from 19000 to 24000 cm−1

“…Σ − -4 Σ − bands of AlC9 , where the sparser density of optogalvanic lines of Ar and Ne made calibration somewhat difficult, and we note that tellurium dimer is being used for calibration in other laboratories[10][11][12][13] . Although the optogalvanic spectrum of uranium14,15 is also useful as a spectral reference in this wavelength range, the greater density of useful lines in the 130 Te 2 absorption spectrum is advantageous for the calibration of smaller wavenumber intervals.…”
