“…Table 6 shows a collection of the experimental results and the theoretical data of Lingott et al [7]. Comparison of the data gives a similar picture as for the lighter bismuth chalcogenides [1][2][3][4]. The experiments confirm the predicted relative order of the seven excited states, and for all states the experimental T e values agree with the predicted values within 400-800 cm À1 .…”

“…1a) consists of short sequences of red-degraded bands with heads in the R-branches. In the light of the results obtained for BiS [2,3] and BiSe [4] and of the theoretical predictions [7], the band system is assigned to the transition C 1 4 R À 1/2 ? X 1 2 P 1/2 which likewise showed up in the spectra of all three lighter bismuth chalcogenides.…”

“…The experimental setup and procedures used for measuring the NIR/VIS emission spectra of BiTe were similar to those described in previous work on BiO [1], BiS [2,3] and BiSe [4]. Chemiluminescence from the Bi x /Te x /O 2 (a 1 D g ) system was studied in a fast-flow system made of quartz and Pyrex glass.…”

“…We identify these bands to be the Dm = 0 bands of the C 1 4 R À vibrational constant of the A 2 4 P 1/2 state and the predicted large transition probability of the C 1 ? A 2 transition [7] as well as on the fact that the same transition has been observed in the spectra of BiSe [4] and BiS [11]. The wavenumbers of the P-branch heads of the 0-0, 1-1, 2-2, and 3-3 bands were corrected by +10.0 cm À1 to get approximate values of the band origins (Table 4).…”

“…In previous work, we have reported on detailed measurements of NIR/VIS emission spectra of the bismuth chalcogenide radicals BiO [1], BiS [2,3] and BiSe [4]. These molecules exhibit X 2 P r ground states with large spin-orbit splittings of about 7000 cm À1 and therefore can be efficiently excited by E ?…”

a b s t r a c t NIR/VIS emission spectra of the bismuth telluride radical, BiTe, were measured in the 3600-20 000 cm À1 region with a Fourier-transform spectrometer. BiTe was produced by reaction of bismuth and tellurium vapors and excited by energy transfer from metastable oxygen O 2 (a 1 D g ) in a fast-flow system. The spectrum of BiTe was found to be markedly different from those of the previously studied BiO, BiS and BiSe radicals. The A 2 4 P 1/2 ? X 1 2 P 1/2 transition which forms the most prominent and extended band system in these molecules was not observed for BiTe, and the X 2 2 P 3/2 ? X 1 2 P 1/2 fine structure transition shows up with a different structure and at much lower wavenumbers than in the spectra of the lighter bismuth chalcogenides. The only common feature is the C 1 4 R À 1/2 ? X 1 2 P 1/2 system which is found in the range 16 500-19 000 cm À1 similar to the three other molecules. Besides the X 2 ? X 1 and C 1 ? X 1 systems, seven other transitions show up by short Dm = 0 sequences only. With help of the data derived from the analyses of the X 2 ? X 1 and C 1 ? X 1 systems and theoretical predictions of electronic and vibrational energies and transition probabilities of the strongest transitions of BiTe by Lingott et al. (2004) [7] the spectra were assigned to the transitions C 1 4
