“…Moreover, Singh et al [15] observed a green emission in the region of 480-530 nm with the maximum at 520 nm and assigned it to a transition from a certain higher state to the C 1 Π state. Recently, Yang et al [19] studied the laser-induced fluorescence spectra of InBr molecule. They recorded the bands of the A 3 Π 0 -X 1 Σ + , B 3 Π 1 -X 1 Σ + and C 1 Π-X 1 Σ systems and reported spectroscopic constants of the C 1 Π state.…”

The emission spectrum of InBr molecule has been recorded in the region 350-400 nm on BOMEM DA8 Fourier transform spectrometer at an apodized resolution of 0.06 cm −1 using microwave excitation technique. About 61 violet degraded and single headed bands have been recorded and are classified into two band systems, viz. A 3 Π0-X 1 Σ + and B 3 Π1-X 1 Σ + . A few new bands have been observed and are fitted in the vibrational schemes of the two systems. Revised vibrational constants have been determined. The vibrational assignments have been confirmed by observing isotope effect due to InBr 81 in the 30 bands of the A 3 Π0-X 1 Σ + system and 19 bands of the B 3 Π1-X 1 Σ + system. The analysis is further supported by calculating the Franck-Condon factor for InBr 79 and InBr 81 molecules. The following vibrational constants (in cm −1 ) have been determined from the analysis:A 3 Π0-X 1 Σ + system: ν00 = 26599.1 ω e = 226.42, ω e x e = 1.24 cm −1 , ω e = 221.19, ω e x e = 0.528 cm −1 . B 3 Π1-X 1 Σ + system: ν00 = 27380.52 ω e = 223.086, ω e x e = 1.446 cm −1 , ω e = 221.19, ω e x e = 0.528 cm −1 .

Abstract.To develop a more efficient plasma light source, molecules are considered as the prime source of radiation, because they can potentially avoid the conversion losses of the low pressure mercury lamp as well as the thermal losses of the high pressure mercury lamps. A candidate to serve as the prime radiator in such a lamp could be Indium Bromide, but spectroscopic data to assess its aptitude is largely unavailable.To increase the knowledge of the spectroscopic properties of these molecules and InBr in particular, an experiment was designed to acquire this information. Laser Induced Fluorescence was used to study the radiative properties of InBr for lighting purposes. Using an innovative method to interpret the measured data, detex plots, more information can be obtained from the spectra. Also the effect of a background gas and plasma was investigated for both a capacitive and an inductive plasma.Mainly the electronic A-state of InBr was investigated. Results include newly identified rotational transitions, vibrational constants, rotational constants for different vibrational levels, band head wave numbers and Franck-Condon factors for various vibrational transitions.

For the first singlet excited states C 1 Π of IIIA group monohalides GaCl, GaBr, InCl, and InBr, a very shallow potential well may exist in the flat potential energy curve, which poses a challenge to the theoretical accuracy. In this study, high-level theoretical calculations have been performed through the Feller-Peterson-Dixon composite approach to study the C 1 Π states, and the obtained spectroscopic constants agree well with the known experimental ones. It is found that the C 1 Π states are sensitive to the size of basis functions, spin−orbit coupling, and strong correlations mainly due to triple excitations. The final results show that the C 1 Π states of GaCl and InCl are quasi-bound with one (v′ = 0) and four (v′ = 0−3) vibrational levels, respectively, being consistent with the experimental findings, whereas the C 1 Π states of GaBr and InBr are repulsive. Our conclusions deny the existence of higher vibrational levels v′ = 1 for GaCl, v′ > 3 for InCl, and v′ ≥ 0 for InBr in previous experimental and theoretical studies of C 1 Π.
